What You Need To Know About Motorcycle Oils

Overview
As with any vehicle equipped with an internal combustion engine, proper lubrication is essential to insure performance and longevity. It is important to point out that not all internal combustion engines are similarly designed or exposed to the same types of operation. These variations in design and operation place different demands on engine oils. Specifically, the demands placed on motorcycle engine oils are more severe than those placed on automotive engine oils. Therefore, the performance requirements of motorcycle oils are more demanding as well.

Though the degree may be debatable, few will disagree that a difference exists between automotive and motorcycle applications. In which area these differences are and to what degree they alter lubrication requirements are not clear to most motorcycle operators. By comparing some basic equipment information, one can better understand the differences that exist.

There are six primary differences between motorcycle and automotive engine applications:

Operational Speed - Motorcycles tend to operate at engine speeds significantly higher than automobiles. This places additional stress on engine components, increasing the need for wear protection. It also subjects lubricating oils to higher loading and shear forces. Elevated operating RPMs also promote foaming, which can reduce an oil's load-carrying ability and accelerated oxidation.

Compression Ratio - Motorcycles tend to operate with higher engine compression ratios than automobiles. Higher compression ratios place additional stress on engine components and increase engine operating temperatures. Higher demands are placed on the oil to reduce wear. Elevated operating temperatures also promote thermal degradation of the oil, reducing its life expectancy and increasing the formation of internal engine deposits.

Horsepower/Displacement Density - Motorcycle engines produce nearly twice the horsepower per cubic inch of displacement of automobile engines. This exposes the lubricating oil to higher temperatures and stress.

Variable Engine Cooling - In general, automotive applications usa a sophisticated water-cooling system to control engine operating temperatures. Similar systems can be found in motorcycle applications, but other designs also exist. Many motorcycles are air-cooled or use a combination air/oil design. Though effective, they result in greater fluctuations in operating temperatures, particularly when motorcycle are operated in stop-and-go traffic. Elevated operating temperature promotes oxidation and causes oils to thin, reducing their load carrying ability.

Multiple Lubrication Functionality - In automotive applications, engine oils are required to lubricate only the engine. Other automotive assemblies, such as transmissions, have seperate fluid reservoirs that contain a lubricant designed specifically for that component. The requirements of that fluid differ significantly from those of automotive engine oil. Many motorcycles have a common sump supplying oil to both the engine and transmission. In such cases, the oil is required to meet the needs of both the engine and transmission gears. Many motorcycles also incorporate a frictional clutch within the transmission that uses the same oil.

Inactivity - Motorcycles are typically used less frequently than automobiles. Whereas automobiles are used on a daily basis, motorcycle use is usually periodic and in many cases seasonal. These extended periods of inactivity place additional stress on motorcycle oils. In these circumstances, rust and acid corrosion protection are of critical concern.

It is apparent that motorcycle applications place a different set of requirements on lubricating oils. Motorcycle oils, therefore, must be formulated to address this unique set of high stress conditions.

AMSOIL Synthetic Dirt Bile Oil Maximizes Performance

Consistent Clutch Feel - Clutch slippage or inconsistent clutch feel can prevent dirt bike riders from riding as fast or effectively as they like. To keep the engine within the power band, riders often modulate the clutch, increasing the opportunity for clutch slippage if low-quality lubricants are used.

AMSOIL Synthetic Dirt Bike Oil's superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. In an extreme simulated-start test, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch feel following 32 simulated race starts, while a leading original equipment manufacturer (OEM)-branded oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts. The clutch plates lubricated with AMSOIL Synthetic Dirt Bike Oil remained clean and in good overall condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL Synthetic Dirt Bike Oil's superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions.

Racing is Research - AMSOIL corporately sponsored supercross and motocross racers identified consistent clutch feel as a key performance attribute. At the time, there was no dirt-bike-specific oil on the market that provided the level of clutch consistency professional and amateur riders demand. Consistent clutch feel is critical to motocross riders during starts to keep the bike from lurching forward prior to the gate dropping. Trail riders, meanwhile, need consistent clutch feel to confidently navigate obstacles without having to shift gears and lose momentum.

In-Depth Product Development - The process to develop Synthetic Dirt Bike Oil relied on a combination of lab and track testing. Clutch feel is inherently subjective, which creates challenges in designing a lubricant that delivers consistent clutch feel. To overcome that challenge, AMSOIL designed The Extreme Simulated-Start Test on Dirt Bikes. The test allows AMSOIL engineers to apply accelerated stress to a dirt bike's clutch in order to monitor clutch feel produced by a candidate lubricant.

The test uses a 2014 Honda CRF450R attached to a dyno. While in second gear, the test administrator holds the clutch at the point just prior to engagement, similar to the way a rider would hold the bike in the gates during a race start. The clutch is then released and the bike is run to fourth gear, simulating the time from the drop of the gate to the first corner in a race. The rear wheel is not allowed to slip during the test, placing additional stress on the clutch. Test administrators look for consistent lever action and feel as they wait to let out the clutch and as they shift the bike through the gears.

AMSOIL Synthetic Dirt Bike Oil was also subjected to extensive on-track testing in the bikes of GEICO/AMSOIL/Honda Factory Connection and other professional riders. A combination of rider feedback and lab testing resulted in the final formulation of Synthetic Dirt Bike Oil. Its performance in lab and track testing dispels the myth that synthetics are "too slippery" and make clutches slip. Results also demonstrate that AMSOIL Synthetic Dirt Bike Oil delivers consistent clutch performance while helping extend clutch life. (Buy Online)

NOACK Volatility Test is a Critical Measurement of Motor Oil Quality

AMSOIL was the first motor oil company in North America to use the NOACK volatility test to measure motor oil quality and performance. Although competing motor oil companies initially paid no attention to NOACK results, the test has since become a critical measurement tool throughout the industry.

Modern engine designs generate more heat than ever, accentuating the importance of the NOACK volatility test for determining an oil's ability to provide an adequate level of protection and performance. More horsepower, turbo chargers and aerodynamic styling have created extremely hot environments that receive less cooling from outside air, and high heat leads to oil oxidation, deposits and thickening in conventional oils.

Top quality for the current API SM motor oils specification, gasoline motor oils cannot experience a weight loss of more than 15 percent in the NOACK test. AMSOIL Synthetic Motor Oils were exceeding modern requirements over 20 years ago, while many current motor oils still have a hard time meeting this minimal requirement, increasing wear, fuel consumption and emissions.

As seen in the graph, AMSOIL Synthetic Motor Oil easily passes the NOACK Test and falls well below the the maximum 15 percent volatilization (burn off) rate dictated by the API SM motor oil specification, while the Royal Purple volatilization (burn off) rate is over 11 percent and the Lucas Oil FAILS the test with a volatilization (burn off) rate of over 40 percent.

AMSOIL Synthetic Motorcycle Oils
AMSOIL synthetic 10W-40 and 20W-50 motorcycle oils give motorcyclists what they need: superior wear protection for high-stress motorcycle engines and transmissions and clutches that stay clean and deposit free.

 
  • Runs cooler - reduces crankcase temperature.
  • Superior 12+ TBN synthetic formulation provides long service life and maximum protection against engine wear.
  • Wet clutch compatible.
  • Recommended for all V-twin and other motorcycle engines.

The AMSOIL Advantage
Motorcycle manufacturers want the best protection possible for their equipment, calling for rugged oils that exhibit high-temperature deposit control additives. AMSOIL Synthetic Motorcycle Oils are specially formulated with the best synthetic basestocks and high-performance additives to provide tough lubricating protection for all four-cycle motorcycle and ATV engines in the most demanding operations.

AMSOIL Motorcycle Oils are formulated for both water-cooled engines and the unique demands presented by air-cooled V-twin motorcyle engines, including Harley-Davidson. Conventional petroleum oils break down and oxidize when faced with high temperatures, such as those experienced when idling in traffic, contributing to the formation of deposits, sludge and varnish. AMSOIL withstands oil breakdown and oxidation in high temperatures, holds contaminants in suspension and keeps engines running cool and clean.

Zinc and phosphorus additives are extremely important to engines faced with high-pressure conditions, especially motorcycle engines, which typically have steep cam slopes, creating high pressure between the parts. In motorcycles, friction modifiers (prevalent in automotive oils) have been attributed to engine start failures, a rough running feel, increased fuel consumption due to higher engine stall speeds and other problems. AMSOIL Synthetic 10W-40 and 20W-50 Motorcycle Oils have beefier antiwear and detergent/dispersant packages with no friction modifiers, keeping motorcycles running smoothly and efficiently, while allowing for extended drain intervals of up to twice the manufacturers' recommendations.

How do other motorcycle oils compare to AMSOIL Synthetic Motorcycle Oils in wear protection?

Wear Protection
AMSOIL submitted popular motorcycle oils to Four-Ball Wear (ASTM D 4172) testing and compared the results to those of AMSOIL Synthetic 20W-50 and Synthetic 10W-40 Motorcycle Oils.

As seen in the graph, none of the popular motorcycle oils compared favorably to the AMSOIL motorcycle oils in wear protection.

AMSOIL Synthetic Motorcycle Oils contain significantly higher levels of zinc and phosphorus than competing oils, and while simply adding more zinc and phosphorus doesn't insure good performance, AMSOIL has formulated motorcycle oils with the best additives in the optimal quantities to provide superior wear protection.

A Four-Ball Wear Test was conducted at 302°F/150°C, a higher temperature that would typically be associated with motorcycle oil operating temperatures in extreme high-performance situations. AMSOIL motorcycle oils protect better in higher temperatures than any of the tested motorcycle oils do, leaving a wear scar up to 80 percent smaller.

Some motorcycle transmissions and engines share a common oil sump, so the engine oil must also provide wear protection to the transmission gears, which, according to Motorcycle Consumer News (Aug. 1998) are subject to high gear surface pressures and gear rotation speeds. The superior performance of the AMSOIL Motorcycle Oils in the Four-Ball Wear Test applies here too.

Motorcyclists will find no better oils than AMSOIL Synthetic Motorcycle Oils.

 

AMSOIL 20W-50 Synthetic Motorcycle Oil vs. Harley-Davidson Screamin' Eagle Syn3 20W-50 Synthetic Motorcycle Oil

The introduction of Screamin' Eagle Synthetic Motorcycle Oil by Harley-Davidson signaled the Motor Companies acceptance of synthetic lubricants as superior performing products for their motorcycles. However, Harley-Davidson V-twin air cooled engines are not so unique in their lubrication requirements that they require a special Harley-only fluid. In fact, Four-Ball Wear Test results indicate that AMSOIL 20W-50 Synthetic Motorcycle Oil leaves a wear scar 40 percent smaller than Screamin' Eagle Syn3 20W-50 Synthetic Motorcycle Oil.

Harley Becomes Smooth Ride With AMSOIL Motorcycle Oil

Terry Campbell of Lincoln, California, a long time Honda rider, bought his 2003 Harley-Davidson Dyna Superglide new. "The biggest thing I noticed was the big twin engines run hot," Campbell said. He initially ran Harley Syn3 in the crankcase, Redline Heavy Shock in his transmission and Redline 75W-140 in his primary. "Wee, the Redline didn't work any better than the Syn3, in fact, my transmission shifted worse. The Harley Syn3 ran too hot, and the Redline was sticky." Campbell said.

He now runs AMSOIL in the engine, transmission and primary. "So, I've been running AMSOIL in all three cavaties," Campbell said. "It has made quite a difference. My engine is running at least 30 degrees cooler, my transmission shifts much smoother and my primary chain is quieter." (read article)

Dear AMSOIL,

I wanted to let you know how happy I am with your AMSOIL 20W-50 Synthetic Motorcycle Oil. I own a 2006 Harley-Davidson Sportster with 5,000 miles on it. Since the bike was new I've only used Harley-Davidson oil in the engine and Sportster gear lube in the transmission and primary chaincase.

After reading your "Study of Motorcycle Oils" I decided to switch to AMSOIL. That was the best thing I've ever done for my Harley-Davidson.

From day one I have had problems down-shifting, especially when the bike was cold. It would hang up between gears and I couldn't get it free before the light at the signal turned green. Very dangerous.

Harley-Davidson told me it was not broken in yet and to stop "granny shifting."

After 5,000 miles it was still doing it. Now, after I started using AMSOIL in my engine and transmission, the problem has ceased completely from the minute I put it in. No matter how easy I down-shift I can't make it hang up between gears.

Thank you so much for your incredible oil. I'll never use any other brand again.

AMSOIL Motorcycle Oil for Harley-Davidson

From the President's Desk...

A situation my daughter, Lyn, told me about recently got me to thinking about how good it is to be able to blend our own oils and have complete control of our own product quality.

Lyn loves to ride motorcycles. She recently purchased a Harley-Davidson bike and took it to the local Harley shop to have our new AMSOIL Motorcycle Oil installed. The mechanic took issue with her not using the oil Harley-Davidson sells, saying, "I'll use AMSOIL motor oil when AMSOIL starts making motorcycles!"

How would you answer a challenge like that? I was pleased to hear Lyn's response. She said, "I'll start using Harley-Davidson motor oil when Harley starts making oil!"

Perfect! The fact is that Harley-Davidson, like so many other "brands" of oil, contract with one or more oil companies to make their lubricants. Often, the decision as to who actually makes a private labeled product is based on low bid, and like almost everything manufactured by a low bidder, short cuts are taken in order to meet the low price.

I understand that Harley-Davidson has contracted with one company for a number of years to make their oil. That's good, but it doesn't change the fact that they make motorcycles, not oil. Now consider all the other private label oils out there. Every manufacturer that makes equipment with an engine has its own name on an oil bottle. That includes all the major auto manufacturers, the makers of motorcycles, ATV's, snowmobiles, lawnmowers, farm equipment, you name it, they all have oils. But none of these equipment manufacturers actually make an oil. They sell oil to make more money, and they often price these oils well above the going rate for competitive lubricants because, like Harley-Davidson, they can specify or create the impression that only their oil be used in their equipment.

Now there's nothing wrong in having a goal to make money, but let's get real here. Why would anyone want to use a product manufactured down to a price rather than a product manufactured up to high quality standards? We have tested a number of these private label motor oils and two-cycle oils and we found many are mediocre quality products. None of them even comes close to performing as well as AMSOIL lubricants, and that's a fact!

I'm not taking shots at Harley-Davidson. They make good motorcycles (although I liked my Goldwing better). And I understand their concern that normal automotive oils not meeting API C specs shouldn't be used in their bikes. But when they imply that AMSOIL Motorcycle Oil is not as good as their brand or I hear that one of their dealers recommended not using AMSOIL, I get a little hostile. Thise kinds of statements are the very reason we introduced our motorcycle oils in the first place. And when we say use our 20W-50 motorcycle oil in V-Twin motorcycle engines, that definately includes Harley-Davidson motorcycles!

Our Motorcycle Products Brochure, G-391, includes wear comparisons of AMSOIL Motorcycle Oils vs other oils, including H-D "Genuine." Both our oils demonstrate superior wear protection over all other tested brands. Interestingly enough, the highest wear scar in this test turned out to be Harley-Davidson's own "Genuine" oil!"

There is a good reason why AMSOIL Motorcycle Oils protect so well against wear. They are formulated with significantly higher levels of zinc and phosphorus, which when included in proper formulation with other high quality additives, provide superior wear protection at the high operating temperatures typical of motorcycles. In addition, synthetic oils inherently reduce sump temperatures so the engines actually run cooler.

The fact is, Harley would do well to have AMSOIL make their oils for them. Then they could be assured that their oil was indeed a superior product. As it is, there may be absolutely nothing wrong with their oil for use in average service, but I guarantee you that as the oil temperature gets hotter, like it does when sitting in traffic on asphalt on a hot summer day, the Harley-Davidson with AMSOIL in the crankcase is going to be far better protected and run far cooler than the bike with H-D "Genuine" oil in it. There's just no two ways about it!

So, my daughter Lyn will be going back to this mechanic armed with the facts about AMSOIL Motorcycle Oils and a few facts about H-D oil. Nobody's going to tell her that her dad's oils are not the very best. She knows better, and she's on a mission to prove her point. Who knows? Knowing Lyn, she might sign up another AMSOIL Dealer in the process!

Honda Gold Wing Has 191,000 AMSOIL Miles on Engine

MSF Motorcycle Safety Chief Instructor Michael R. Douglas, of Anaheim CA, wrote, "I currently own a 1989 Honda GL1500 Gold Wing motorcycle. My Gold Wing has 267,025 miles on it. For the past 191,000 miles I have been using AMSOIL Synthetic 10W-40 Motor Oil. I have been changing the oil and filter at intervals of approximately 10,000 miles."

"Recently, I decided to pull the motorcycle apart and have it painted and chromed. After pulling the valve covers off, I was extremely surprised to see how clean the valve train was. The green paint sprayed on by Honda over 10 years ago is still visible. In the rear of the engine by the clutch, is a small piece of plastic 90-degree tube, which allows oil to return to the front half of the engine. With this many miles, this tube is usually either partially or completely plugged with clutch debris and other deposits. If this happens, the front end is starved for oil. The tube in my engine was spotless!"

"I also use AMSOIL synthetic gear lube in the final drive assembly. Keep up the great work! Outstanding products!"


Gold Wing Owner Enjoys Increased MPG

Ralph Sites, a police officer in Rutsburg, Virginia, said he put AMSOIL 10W-40 Synthetic Motorcycle Oil in his 2002 GL 1800 Honda Gold Wing when it had 4,550 miles on the engine.

"I had been getting 30 miles per gallon," Sites said. "I was supposed to be getting 40 to 45 miles per gallon."

His first oil change to AMSOIL improved his gas mileage to 38 miles to the gallon, he said. At 6,500 miles on the engine, he was getting 40 miles per gallon. He replaced the final drive oil with AMSOIL 75W-90 Synthetic Gear Lube.

"I switched to AMSOIL for the long-term gain. The improved gas mileage was just a bonus. AMSOIL is cheaper than Honda's synthetic and I don't have to change it as often. It's a win-win situation."

He bought the bike new in January 2002, and after putting 12,000 miles on it he estimated he'd saved more than $100 in a matter of a few months because of the increased mileage he got after switching to AMSOIL.


AMSOIL Motorcycle Oil Makes Honda Goldwing Purr

Ken Burkhalter trusts the quality and performance of AMSOIL motor oils, lubes and filters, but he has been newly impressed with AMSOIL products in his 1999 Honda Goldwing GL1500SE. He purchased it with 15,000 miles on the engine. He put 5,000 miles on the oil and fluids installed by the dealer he bought the bike from and then installed AMSOIL 10W-40 Synthetic Motorcycle Oil. "Upon riding the bike after the change I was blown away," Burkhalter said. "Words alone cannot describe the remarkable performance change."

He reports the engine starts easier and quieter and idles significantly faster.

"I'll have to adjust the idle speed back down," he said. "It runs like everything is made from silk. The engine is so quiet you can barely hear it at 70 mph, and the smooth sound it makes is so stunning, I have been driving with my radio off just to enjoy the engine purr."

Besides the purring of the engine, Burkhalter experienced an immediate improvement in shifting ease on the Goldwing. "I thought it might be my over-fertile imagination, but looking at the shop manual closer I find that the transmission runs in the engine oil (not seperate) so the extreme smoothness. ease of shifting and lack of gear gnashing can only be attributable to the use of the AMSOIL motorcycle oil.

AMSOIL Keeps Honda CR85 on the Track

Motocross racer Chris Price of Yadkinville, North Carolina, competes on a 2005 Honda CR85 at a couple of local tracks. One day at the track. Mike Price (chris's dad) installed a new clutch on his bike before racing began.

"I forgot to check the clutch for play because the plates will swell when they are new," said Mike. He said he could hear the engine screaming as soon as the 11-year-old racer left the gates. The motor nearly quit altogether and Price fell to last place, but he didn't stop riding.

"I finished the whole seven laps and took second place, the clutches held together but were slipping the whole time" said Price.

After getting the bike back to the trailer the Prices changed the oil and checked the clutches.

"Everything looked great. My dad said if it wasn't for AMSOIL 10W-40 Motorcycle Oil in the transmission, the clutches would have burned out after two laps," said Price.

Price uses AMSOIL Dominator in the engine and an AMSOIL Power Sports Air Filter along with the AMSOIL Motorcycle Oil in the transmission.

"The oil never broke down in the severe heat that built up in the clutches, and AMSOIL Dominator is the best that has ever been made," said Mike "Customer for life."


Hayes Diesel Powered Motorcycles Depend on AMSOIL

Hayes Diversified Technologies USA is working on development of commercially available motorcycles, tentatively scheduled for release by early 2008. The company is so impressed with AMSOIL that these motorcycles will come factory-filled with AMSOIL synthetic lubricants. This quote from HDT's website sums up their experience with AMSOIL: "With over a year of testing, we have found that AMSOIL products continually outperform all other lubricants. AMSOIL provides improved performance, increased fuel economy, lower oil consumption and significantly reduced engine wear in all operating conditions." (read article)


AMSOIL Equipped Motorcycle Wins Fuel Economy Challenge

AMSOIL Synthetic Lubricants figured prominently in the Vetter Fuel Economy Challenge held May 13 in northern California, where a diesel-powered motorcycle using AMSOIL products won by achieving 128.24 mpg. Many of the other bikes also relied on AMSOIL products to help achieve results nearly as impressive.

Winning driver Fred Hayes of Hayes Diversified Technologies (Hayes-DT) completed the challenge riding the company's MD670 F2 diesel-powered motorcycle (pictured below). Hayes bested the next closest competitor by over 18 mpg using biodiesel fuel, a lightweight motorcycle design (370 pounds dry) and AMSOIL synthetic lubricants throughout. (read article)

WHY AMSOIL?

A Commitment to Excellence
As a jet fighter squadron commander Lieutenant Colonel Albert J. Amatuzio had ample opportunity to witness synthetic lubricants in action. These oils are used exclusively in jet engines because of three extraordinary performance characteristics: an ability to reduce friction and wear on engine components, an ability to function dependably at severe temperature extremes and an ability to withstand rigorous and lengthy engine operation without chemical breakdown.

Recognizing that these same benefits would prove invaluable in combustion engines, Amatuzio began conducting serious research in 1963. By 1966 he had formulated a synthetic motor oil and put it to use in vehicles in northern Minnesota. Throughout the late '60s Amatuzio continued his research and development and sold commercially available synthetic oils under a variety of names. In 1970 he incorporated his own name into a commercially sold product called AMMOIL. In 1971 this product name was changed to AMZOIL and it continued to be sold commercially. The true milestone came in 1972 when AMZOIL became the first synthetic motor oil in the world to meet American Petroleum Institute criteria. The new lubricant performed like no other before it. When the first can appeared on the market in 1972, it signaled the birth of an entire industry. AMSOIL synthetic lubricants have expanded the boundaries of lubrication science and redefined the performance possibilities of modern machinery and engines. (read story)

Improve Fuel Efficiency With AMSOIL Synthetic Lubricants

Short supplies and ever-increasing demand have pushed crude oil barrel proces to record highs over the summer, and motorists have been directly affected. Gasoline is one of the primary products produced from crude oil, and pump prices are directly affected by the prices refiners pay for crude oil. In fact, the average price per gallon of gasoline reached levels over 50 cents higher than last summer, causing motorists to alter their driving habits and look for every and any way to get the most for their fuel dollar.

According to the U.S.Energy Information Administration (EIA). the price of crude oil represented an average of 42.6 percent of retail gasoline prices between 2000 and 2003, with refinery processing cost, marketing and distribution costs and gasoline station costs and taxes comprising the balance. It is the volatile of crude oil prices that is most responsible for fluctuating gasoline prices. AMSOIL Synthetic Motor Oils have been shown to yield significant increases in fuel economy over conventional motor oils. Petroleum based lubricants are composed of irregular molecules of various sizes that create excess friction, in addition to the friction generated by moving parts. The vehicle's engine must burn extra fuel to overcome this friction, decreasing fuel economy. AMSOIL synthetic lubricants, on the other hand, contain only smooth, uniform molecules that effectively reduce friction and improve fuel efficiency.

Conventional lubricants are also very suseptible to volatility. When the oil's lighter molecules volatize during hot operating conditions, viscosity increases and the oil becomes more difficult to pump, consuming more energy and reducing fuel economy. Because AMSOIL synthetic lubricants contain uniformly sized molecules, they resist volatization, maintain their viscosity and allow more fuel to be used for vehicle propulsion, improvong fuel economy.

The use of AMSOIL synthetic motor oils, gear lubes and drivetrain fluids can have a profound impact on fuel economy. Industry tests demonstrate that an average passenger car can conservatively decrease its fuel consumption by two to five percent by switching to synthetic lubricants, while independent testing shows that trucks can decrease fuel consumption by 8.2 percent. Many AMSOIL customers report even larger gains in fuel economy.

According to the U.S. Federal Highway Administration, total U.S. fuel consumption was 162.3 billion gallons in the year 2000. Consider the savings if every American vehicle converted to AMSOIL synthetic lubricants and gained a five percent increase in fuel economy. It would equate to a savings of 8.115 billion gallons of fuel each year, at a pice savings of $24.35 billion (at $2 a gallon).

According to the U.S. Department of Transportation, the average passenger vehicle burned 587 gallons of gasoline in 2002. At a price of $3 a gallon, the average vehicle owner spends $1,761 on gaoline each year. With a five precent fuel economy improvement afforded with AMSOIL synthetic lubricants, the motorist saves $88.05 a year in fuel expenses. That's enough to cover the price of a year's supply of AMSOIL Synthetic Motor Oil and Ea Oil Filters, with money left over.

In addition to fuel savings, AMSOIL synthetic lubricants also allow motorists to reduce oil usage through extended drain intervals, while significantly reducing friction and wear, improving engine performance and extending equipment life.


How Much Money Can AMSOIL Save You?

For a vehicle driven 20,000 miles per year and receiving 20 mpg:

Vehicle burns 1,000 gallons/year at a cost of $3,000 (at $3 a gallon).

5 percent fuel economy increase with AMSOIL = 1 mpg.

Vehicle now receives 21 mpg.

Vehicle now burns 952 gallons/year at a cost of $2,856 (at $3 a gallon).

48 less gallons/year for a savings of $144/year.


For a vehicle driven 20,000 miles per year and receiving 15 mpg:

Vehicle burns 1,333 gallons/year at a cost of $3,999 (at $3 a gallon).

5 percent fuel economy increase with AMSOIL = 0.75 mpg.

Vehicle now receives 15.75 mpg.

Vehicle now burns 1270 gallons/year at a cost of $3,810 (at $3 a gallon).

63 less gallons/year for a savings of $189/year.


For a vehicle driven 20,000 miles per year and receiving 10 mpg:

Vehicle burns 2,000 gallons/year at a cost of $6,000 (at $3 a gallon).

5 percent fuel economy increase with AMSOIL = 0.5 mpg.

Vehicle now receives 10.5 mpg.

Vehicle now burns 1,904 gallons/year at a cost of $5,712 (at $3 a gallon).

96 less gallons/year for a savings of $288/year.


Is Your Synthetic Motor Oil Really Synthetic?

Recently, Castrol and Mobil brought the debate over what is "synthetic" into view, as Mobil challenged Castrol's replacement of polyalphaolephins (PAOs) with hydroisomerized waxes (hydrocracked petroleum basestocks) in their synthetic formulations. Exactly one year after the National Advertising Division of the Council of Better Business Bureaus' ruling upholding Castrol's position that wax isomerates could be called synthetic, Petro-Canada (a large provider of basestocks to oil marketers) advertised it would be referring to its very high viscosity index (VHVI) basestocks as a synthetic in the North American market. These products fall into the same API group (Group III) as wax isomerates, but could vary significantly in quality from wax isomerates. This market roar by Petro-Canada has carried a quiet undertone of moves from PAO to VHVI technology by several engine oil marketers. (read entire article here)


The Myth of the 3,000 Mile Oil Change Interval

AMSOIL represented the lone voice for extended drain intervals in America for over 30 years, recommending 25,000-mile/one-year drain intervals. While extended oil drain intervals have been common in Europe for years, other American motor oil companies have mostly avoided recommending them, preferring instead to stick with 3,000-mile recommended intervals despite the contrasting recommendations of vehicle manufacturers and European motor oil companies.

In fact, Marc Graham, president of Pennzoil-Quaker State-owned Jiffy Lube International, was quoted in a 2001 Lubricants World interview as saying, "At [Pennzoil-Quaker State] we use a number internally that if we [shorten the drain interval] by 100 miles [for each car serviced], it would mean an additional $20 million in revenue for the company." He also explained that "if we could move our customers to get one more oil change per year, it's worth $294 million for the oil change alone and $441 million in revenue, when you include the ancillary products and services customers typically buy along with the oil change."

Today, with vehicle manufacturers recommending longer and longer drain intervals and the increasing use of oil monitoring systems, the practice of extending drain intervals has become more mainstream and forced more motor oil companies to take notice. (read entire article here)

Motor Oil Test and Comparison - The Most Comprehensive Test Results Ever Published by AMSOIL


AMSOIL Synthetic 15W-40 Diesel Oil Field Study - Nordic Waste Refuse Hauler

Fleet owner switches from Shell Rotella T 15W-40 Diesel Oil to AMSOIL Synthetic 15W-40 Diesel Oil after seeing increased performance, protection and cost savings

In order to test the performance capabilities of AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil (AME), AMSOIL sought a partner with a fleet that operated in truly severe conditions. The perfect match was found in Duluth, Minnesota based Nordic Waste. Nordic Waste operates a fleet of 10 International refuse haulers, providing trash and recycling pickup to residential and commercial customers in the greater Duluth/Superior, Wisconsin region. Nordic's trucks operate in the bitter cold of sub-zero winters as well as on humid summer days that can top out at over 90 degrees F. In addition, Lake Superior's influence on the areas weather patterns can create extreme temperature swings just miles from the lake, something Nordic's trucks encounter regularly. The company's fleet runs 12 hours a day with frequent stops and redlined starts, all while hauling up to 22,000 lbs. of refuse and navigating the seriously steep hills of Duluth. Nordic Waste was initially installing Shell Rotella T 15W-40 before switching to AMSOIL. (read more)


Dodge Dually Surpasses 633,000 Miles With AMSOIL Lubes

Brad Walthour of Sunbury, Ohio speaks from experience when he talks about the qualities and benefits of AMSOIL lubes and filters.

"I rely solely on AMSOIL products to protect my investment in a wide range of outside temperatures on various and challenging terrain," Walthour said. He uses AMSOIL Cold Flow Improver during the cold months. "The fuel has never gelled," he said. "The engine and transmission have never been dismantled, rebuilt or replaced." He averages 26 mpg an 55 miles per hour when he's not towing anything and 11.5 to 14 mpg when towing. He calculates his oil change savings with AMSOIL products to be $300 a year, which doesn't include the added protection against wear and extreme temperatures. (read more)


Truck Driver Takes Big Savings to the Bank Using AMSOIL Products

Terry Anderson Jr. of Chesapeake, Virginia saves money, time and fuel using AMSOIL products.

In fact, he saved $5,679 the first year he switched to AMSOIL lubes, filters and additives.

TAKING SAVINGS TO THE BANK - Terry Anderson with his 2005 Peterbilt dump truck. Anderson reports savings of $5,679 in one year using AMSOIL lubes and filters.

Anderson, owner of Terry Anderson Jr. Hauling Inc., owns and operates a 2005 Peterbilt dump truck with a Cat C-7 engine. He first installed AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil and an AMSOIL Ea Oil Filter in the truck. About a month later, he installed an AMSOIL By-Pass Filtration System.

"initially, I was concerned about the upfront cost of about $400, but soon found out it was money well spent," he said.

Used oil analysis at 10,000 and 25,000 miles deemed the oil suitable for continued use, and he continued to run on the same oil.

"I changed my full flow filter after the second sample was sent in," Anderson said. "The money I saved on oil alone in the first 25,000 miles paid for the by-pass filter system." At one year, and more than 50,000 miles on the same oil, a third oil analysis reported the oil good for continued use. "The savings in the oil changes alone is enough to justify using AMSOIL and the by-pass filter system," Anderson said. "More surprising was the increased fuel efficiency I saw on a daily basis."

He typically changes the oil in the Peterbilt four or five times a year at $159 each change. "That is $759 a year." He said. "I didn't have to get my hands dirty changing the oil at all for a year thanks to AMSOIL and the by-pass filter system."

Anderson also realized increased fuel efficiency. "After changing my Peterbilt over to AMSOIL lubricants and filters, I saw an increase in my fuel efficiency of one mile per gallon," he said. His fuel efficiency increased again when he used AMSOIL Diesel Concentrate and Cetane Boost. "MPG is huge in my world," Anderson said. "The more miles I can go on one gallon, the more money I put in the bank."

With diesel fuel prices being so high, AMSOIL lubricants, filters and additives have saves Anderson's company about $30 a day in improved fuel efficiency.

Savings he realized in the first 15 days with AMSOIL products paid for his initial investment, Anderson said. "The remainder of the year that $30 a day went straight to the bank along with the savings from the extended drain intervals." (see savings chart)


Trucker Saves Thousands with AMSOIL

Blake Thompson is one happy trucker - in front of his first tractor trailer that he switched over to AMSOIL products.

Blake Thompson is one happy trucker.

Using AMSOIL products in his diesel engines saved him $5,000 in fuel costs in one year.

In 2006, Thompson was a diesel mechanic in Fortville, Indiana when he fist became familiar with AMSOIL products. Thompson had a dream of owning his own trucking company.

In November 2007, Thompson bought his first diesel tractor - a 1999 International with an M11 Cummins engine, an Eaton 4-9 transmission, five low-range gears, four high-range gears and a twin screw (two differentials) rear-end. "It was in beautiful shape with 580,000 original miles," Thompson said.

Thompson is now a local hauler with two trailers. He uses one for hauling wood products - sawdust and wood chips, and the other for agricultural products, including corn and soy beans. The truck and tractor have a maximum gross weight of 80,000 pounds.

Thompson had his truck for only a short time before he switched to AMSOIL. With 590,000 miles on his tractor, he signed on the dotted line to become a commercial account. He purchased AMSOIL Engine Flush (AEF) and twin packs of AMSOIL 15W-40 Heavy Duty Diesel and Marine Oil (AME).

Thompson said he is more than happy he switched to AMSOIL products. He reports that while towing his hopper trailer his fuel mileage increased from 5.5 to 6.0 miles per gallon. While towing his walking floor trailer the fuel mileage increased from 6.0 to 6.5 miles per gallon.

Oil analysis at 10,000 and 20,000 miles showed the oil was "good for continued use." Typical oil drain intervals for the big diesel engine is 20,000 miles.

Thompson was spending $75,000 a year on fuel. After investing $500 in AMSOIL products, he is spending $69,500 a year on fuel. That's a savings of $5,000 per year!

Thompson is considering using oil analysis to extend his oil drain intervals even further, but Thompson said he is so happy about the fuel savings that he is satisfied changing the oil at his current drain intervals.

Thompson also uses AMSOIL Synthetic 5th Wheel Grease (GFW) "because it goes on easy and stays where you put it." He can also see the difference in the spring shackles and king pins with AMSOIL Synthetic Heavy Duty Grease (GHD). Thompson says he used to have to pump several pumps, with brand X grease, before the grease started squeezing out. Now when he starts to pump the grease gun, the grease immediately starts to squeeze out of the joints. "That shows that the AMSOIL Heavy Duty Grease stays where you put it."

Thompson's business is growing. He recently bought another used tractor that has more than 470,000 miles on the engine. He says he will use AMSOIL 15W-40 Heavy-Duty Diesel and Marine Motor Oil in that one too, and he is eager to try the gear lube in his bearings, transmission and differentials.

Thompson has continued to buy AMSOIL 15W-40 Heavy Duty Diesel and Marine Motor Oil, Oil Sample Kits, Heavy Duty Grease and 5th Wheel Grease.


AMSOIL 409,000-Mile Oil Drain Interval Mack Engine Teardown

Haywood Grey went 409,000-miles without an oil change in his Mack E7-400After 409,000 miles without an oil change, the AMSOIL-protected Mack E7-400 engine in this truck was as wear-free as an engine in comparable service treated to TWENTY TIMES the oil changes.

COLONIAL HEIGHTS, VIRGINIA - "I didn't see any surprises in there at all. Based on my experience with AMSOIL Motor Oil, it came out the way we expected," said owner/ operator Haywood Gray (left) of his 1990 Mack E7-400 engine. It came out in good shape, exactly what you'd expect for a well-maintained engine with 630,000 miles. Yet the engine's oil had not been changed for 409,000 miles!

Gray began using AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil (AME) in the E9-400 V-8 engine of his first truck, a 1984 Mack, after the engine accumulated 45,000 miles. For 280,000 miles, Gray changed his oil at 40,000-to 60,000-mile intervals though his oil analysis reports showed, without exception, that the oil was good for continued use. At 325,000 miles, Gray increased his oil drain interval to 100,000 miles. The engine was torn down at 600,000 miles when Gray decided to sell the truck. (read more)

Nordic's trucks operate in the bitter cold of sub-zero winters, as well as on humid summer days that can top out at over 90 degrees F. The fleet runs 12 hours a day with frequent stops and redlined starts, all while hauling up to 22,000 pounds of refuse and navigating the seriously steep hills of Duluth. (read more)


AMSOIL Products Improve Efficiency and Reduce Operating Costs for Gerlach Trucking

AMSOIL INC., in conjunction with Gerlach Trucking of Erskine, Minnesota, conducted a field demonstration of its Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, Super Duty Oil Filters and Dual-Gard filtration system equipped with BE-110 by-pass filtration elements.

The test vehicle was a 1995 Freightliner FLD-120 powered by a Detroit 60 Series diesel engine and utilized mainly in long-haul transports. The testing covered a two-year period and the vehicle accumulated 212,326 total miles.

The goals for this demonstration included showing that the use of AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil, in conjunction with the AMSOIL Dual-Gard filtration setup and SDF Oil Filters, would result in improved efficiency, reduced operating costs and environmental benefits when compared to conventional petroleum lubricants and filtration methods. As mentioned, the evaluation was conducted using a 1995 Freightliner FD-120 equipped with a Detroit 60 Series diesel engine. The AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil was sampled at the manufacturer's suggested oil drain intervals and monitored through the use of oil analysis to ensure its continued serviceability. The full-flow filtration units were also monitored and replaced at 12,000- to 15,000-mile intervals, while the By-Pass units were monitored and replaced at 24,000- to 30,000-mile intervals.

AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil is Correct Choice For Jeff Foster Trucking

With the help of Jeff Foster Trucking Inc. of Superior, WI, AMSOIL put its Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD), as well as its Dual-Gard filtration system, to the test.

Ten 1996 Kenworth Class 8 tractors used as interstate freight hauling vehicles and equipped with Cummins N-14 ESP3 diesel engines participated in the demonstration. Five trucks equipped with AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, AMSOIL BMK-12 Filter mounts and BE-110 By-Pass filtration elements utilized 120,000-mile oil drain intervals,20,000-mile full- flow oil filter change intervals and 40,000-mile By-Pass filter change intervals, while the other five trucks continued using petroleum motor oil, utilizing 20,000-mile oil and filter drain intervals.

The objective of the field demonstration was to prove that using AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, together with the AMSOIL Dual-Gard filtration system, would result in a reduction in operating expenses when compared to the use of conventional petroleum lubricants and filtration methods. Verification will be demonstrated through increased fuel economy, extended drain intervals, reduced oil consumption and reduced maintenance. (read more)


AMSOIL Proves Superior in Clark County Field Test

School BusIn order to demonstrate the effectiveness of AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil and the AMSOIL Dual-Gard filtration system in reducing operating expenses, AMSOIL and Direct Dealer Bill Andes began an ongoing field test in October 1998 with the bus fleet of the Clark County Board of Mental Retardation and Developmental Disabilities (MR/DD) in Springfield, Ohio.

Participating in the field test are three 1997 International 3800 school buses, two equipped with International 466 diesel engines and one with an International 466E diesel engine. Each had previously been running a conventional petroleum-based oil.

Engine wear rates have decreased significantly since changing to AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil. High temperature operating conditions have also been reduced. This leads to enhanced engine protection, and ultimately, to longer engine life. Because the engines have been operating more efficiently, three to five percent gains in fuel economy have also been realized. The chart below compares the levels of wear particles present in the previous conventional oil with the levels present in the AMSOIL as of May 2001. The condition of the AMSOIL at various testing intervals is documented below. (read more)


Diesel Oils Evolve With Diesel Engine Designs

The latest round of emission standards went into effect in 2007, requiring even more stringent NOx and particulate emissions reductions. While low levels of EGR technology (10-15 percent) were successfully applied in diesel engines to meet 2002 NOx emissions standards, most manufacturers incorporated increased EGR rates of 25-35 percent in order to meet 2007 standards. Increased EGR rates mean 2007 and newer diesel engines run hotter than their predecessors, requiring diesel oils meeting the latest API CJ-4 specification to be formulated with improved oxidation resistance properties to prevent thermal runaway and maintain engine protection.

Decreasing the level of sulfur in diesel fuel has been determined to be the most cost effective way to decrease particulate emissions. The introduction of ultra low sulfur diesel (ULSD) fuel in June 2006 dropped diesel sulfur levels from 500 ppm to 15 ppm in order to meet 2007 particulate limits, provide compatibility with NOx after treatment systems and enable high EGR rates.

In addition, in order to further reduce particulate emissions, diesel particulate filters (DPF's) were incorporated into all 2007 and newer American diesel engines, and CJ-4 diesel oils are faced with the challenge of balancing engine protection with DPF life. Increased EGR. although effectively decreasing NOx emissions, results in less efficient combustion and increased levels of soot, and some of it finds its way into the engine oil. (read more)


AMSOIL Boosts CJ-4 Diesel Oil Offering

Upgraded formulation, new viscosity and longer drain intervals provide excellent value

AMSOIL has reformulated its Premium API CJ-4 Synthetic 5W-40 Diesel Oil (DEO). In addition, AMSOIL now offers a new 15W-40 Premium API CJ-4 Synthetic Diesel Oil (DME). These exceptional diesel oils provide a level of protection afforded only by a truly high quality synthetic oil - and do so over drain intervals of 3X (3 times) OEM recommended drain intervals. They are the premium choice for API CJ-4 emission-compliant diesel oil required by model-year 2007 and newer diesel engines. Formulated for vehicles fitted with exhaust treatment devices, DEO and DME are also backwards compatible, offering maximum protection to all diesel applications. (read more)


Superior Filtration Plays Important Role in Engine Protection

A great deal of emphasis is placed on the importance of using the most advanced high-quality lubricants, but superior filtration is often taken for granted. The general attitude displayed by many consumers is to use whatever is cheapest, even when they've invested is superior lubrication. While AMSOIL synthetic motor oils provide unbeatable protection, performance and economy, they require the assistance of filtration. Without filtration, by-products from the combustion process and abrasive materials ingested from the air will ultimately destroy an engine. (read more)

AMSOIL Synthetic Gear Lube Outperforms Valvoline Gear Lube

AMSOIL 75W-90 Synthetic Gear LubeHigh quality gear oils must lubricate, cool and protect geared systems. They must also carry damaging wear debris away from contact zones and muffle the sound of gear operation. Commonly used in differential gears and standard transmission applications in commercial and passenger vehicles, as well as a variety of industrial machinery, gear oils must offer extreme temperature and pressure protection in order to prevent wear, pitting, spalling, scoring, scuffing and other types of damage that result in equipment failure and downtime. Protection against oxidation, thermal degradation, rust, copper corrosion and foaming is also important.

AMSOIL submitted its 75W-90 Synthetic Gear Lube (AGR) and Valvoline 75W-90 Gear Lube to an independent laboratory for quality comparison tests. The gear lubes were tested according to ASTM testing procedures in several critical performance areas, including oxidation resistance, viscosity retention and cold temperature fluidity. Oxidation resistance was measured using the L-60-1 Thermal Oxidation Stability Test, viscosity retention was measured using the KRL Shear Stability Test and cold temperature fluidity was measured using the Brookfield Viscosity Test. Additional load carrying, wear, extreme pressure and scoring protection tests were performed exclusively on AMSOIL 75W-90 Synthetic Gear Lube using the L-37 High Torque Axle Test and the L-42 High Speed Axle Test.

Why Motor Oil Deteriorates

It is common knowledge that, at some point, engine oil must be changed. It's something that is preached relentlessly to vehicle owners by vehicle manufacturers, quick lubes and oil companies. But consumers are widely unaware of what exactly makes oil changes necessary.

Many factors contribute to a motor oil's demise, but it is essentially the accumulation of contaminants in the oil and chemical changes in the oil itself that make a motor unfit for further service. With time, it is inevitable that the oil will be contaminated by dirt or sludge, or succumb to the extreme pressures or temperatures found inside an engine. AMSOIL Motor Oils are formulated with the industry's most advanced synthetic base stocks and additive packages to combat the forces that deteriorate conventional oils. (read more)


What is the NOACK Volatility Test?
Volatization is a term used to describe what happens to a fluid as it is heated to the point it begins to "boil off." Upon reaching a certain temperature, oil will begin to lose some of its lighter weight molecules as they "boil off" and leave heavier weight molecules behind. Not only does this cause higher oil consumption, this process can also cause increased viscosity making the oil more difficult to circulate through the lubrication system. (read more)

FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
