AMSOIL Ea Motorcycle Air and Oil Filters

Second to None Air and Oil Filtration for Your Motorcycle

AMSOIL INC. revolutionized the filtration industry with its introduction of AMSOIL Ea Air and Ea Oil Filters. For the first time exclusive nanofiber technology - the same technology used in the Abrams M1 tank and other heavy duty applications - was made available for automotive applications. Now, AMSOIL has made this outstanding new technology for motorcycles.

Nanofiber Basics - Because the nanofibers in AMSOIL Ea Motorcycle Air and Oil Filter media are so small, there are more pores per square inch, allowing for higher dirt-holding capacity and lower pressure drop compared to traditional filter medias. Thinner media fibers produce more uniform pore size distribution, improving the filter's overall ability to capture and retain particles.

Air Filtration Basics - An engine requires air for combustion, but the air drawn in through the induction system is loaded with contaminants. There are over 400 tons of suspended dirt and other contaminants in a cubic mile of air over a typical city. The concentration can be even higher in rural areas where there is frequent travel on unpaved roads. The dirt and contaminants drawn into an engine from the air are the leading causes of engine wear.

The function of the air filter is to trap and hold these wear causing contaminants without restricting air flow. As the filter traps more and more contaminants, air flow becomes restricted, smothering the engine and diminishing performance. The more wear causing contaminants a filtration media traps and holds, while still allowing optimum air flow, the better the filtration media.

The nanofiber technology used in AMSOIL Ea Filters surpasses all other technology in efficiency, capacity and service life. With AMSOIL Ea Air Filters, dust and sub-micron particles remain on the surface and are trapped in the nanofibers, preventing particles from lodging in the filter media depth. This produces higher efficiency and higher capacity, extending engine and filter life and reducing engine wear.

AMSOIL Ea Motorcycle Air Filters

The filtration media in the AMSOIL Ea Motorcycle Air Filters is pleated and has epoxy-coated wire on the face and back of the media for additional strength and stiffness. High quality plastisol potting compounds bond the pleat packs to the plastic or aluminum side plates. The S&S (aftermarket engine and carburetor manufacturer) style round filters are manufactured with high-quality plastisol that bonds the media to the wire backing and sealing area.

Superior Filtration - The synthetic nanofiber media featured in AMSOIL Ea Motorcycle Air Filters have sub-micron diameters and small inter-fiber spaces, resulting in more contaminants being captured on the surface of the media and lower restriction. Cellulose, wetted gauze and foam filters have larger spaces between the media that cause contaminats to load in the depth of the filter, resulting in airflow path plugging, higher restriction and lower capacity.

Cleanable for Long Service Life - AMSOIL Ea Motorcycle Air Filters are cleanable, providing unsurpassed protection and long service life. AMSOIL Ea Motorcycle Air Filters should be cleaned every year or according to operating conditions. Operation in extremely dusty or dirty environments may require more frequent cleaning. Ea Motorcycle Air Filters should be changed every four years.

Cleaning Instructions - AMSOIL Ea Motorcycle Air Filters are cleaned in the same manner as AMSOIL Ea Air Filters for cars and light trucks: with a vacuum or shop air.

To clean with a vacuum, place the filter on a flat surface and carfully vacuum the filter media on the dirty side where the incoming airflow enters the filter.

To clean with shop air, hold the filter with one hand and carefully blow the filter media at a 45-degree angle on the clean side of the filter using low pressure (15 to 20 psi) shop air. Using too much air pressure will damage the filter media.

Superior Alternative - AMSOIL is producing Ea Motorcycle Air Filters for the most popular Harley Davidson models from 1988 to the present, including motorcycles equipped with S&S carburetors and air cleaner housings.

Oil Filtration Basics

Clean oil is vital to engine performance and durability. Oil must lubricate, cool and clean the engine as it circulates. In order to remain effective, it must be filtered as it cycles.

The filter is connected to the engine sump, which contains the oil pump. Full-flow filters pass all the oil output from the pump through the filter.

The function of the oil filter is to remove the contaminants introduced into the lubricating oil and prevent them from reaching sensitive engine parts without restricting normal oil flow to the various points requiring lubrication. Internal sources of contamination include wear products from the rubbing surfaces of the engine, blow-by gases leaking past the rings of the pistons and degradation of the oil itself. A filter must perform well in the areas of efficiency, capacity, flow and life.

AMSOIL Ea Motorcycle Oil Filters

AMSOIL Ea Motorcycle Oil Filters feature a specially constructed silicone anti-drainback valve and a nitrite sealing gasket to go along with the full-synthetic Ea nanofiber media. The anti-drainback valve provides excellent protection during startup and remains flexible in all temperatures, and the nitrile sealing gasket resists chemical breakdown, providing excellent durability and ensuring long filter life. AMSOIL Ea Motorcycle Oil Filters are fluted for easy removal from the motorcycle and are available in a chrome-plated alternative to the normal black filters.

Superior Filtration - The unique construction and full-synthetic media of AMSOIL Ea Motorcycle Oil Filters allow them to provide unmatched performance in motorcycles and other power sports equipment. EaOM Filters last longer, stop smaller dirt particles and offer less restriction than other filters. Ea Motorcycle Oil Filters provide filtering efficiency of 98.7 percent at 15 microns, outperforming the best cellulose/synthetic blend media on the market.

Superior Alternative, Multiple Applications - AMSOIL Ea Motorcycle Oil Filters provide unsurpassed protection for motorcycles, ATVs, four-stroke personal watercraft, four-stroke snowmobiles and four-stroke outboards. AMSOIL is producing Ea Motorcycle Oil Filters manufactured for the most popular motorcycle and power sports applications.

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.

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.
