AMSOIL Synthetic 15W-40 Diesel
Oil Field Study - Nordic Waste Refuse Hauler
Synthetic 15W-40 Diesel and Marine Oil delivers maximum performance,
protection and cost savings for Nordic Waste's fleet of refuse
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.
As if the geographic
challenges aren't enough, perhaps the greatest strain these
refuse haulers' engines face is dumping the refuse. This action
requires the engine to remain near of above redline throughout
the process and shakes the truck enough to nearly lift the
front tires off the ground. Nordic's trucks dump their contents
twice daily, challenging the oil's shear stability on a regular
Waste was chosen to participate in this study not only because
refuse haulers in general provide a severe operating environment
for oil, but also because of the particular engine in the
company's 2006 International 7400 rear loading truck. Notoriously
hard on oil, the Navistar DT466 diesel engine is a 7.6L inline
six-cylinder designed specifically for use in large, commercial
International trucks. Nordic Waste initially
installed Shell Rotella T 15W-40 (239 hours), and the
oil was monitored through oil analysis for the duration of
the drain interval. For the subsequent drain interval,
Nordic installed AMSOIL
Synthetic 15W-40 Heavy Duty Diesel and Marine Oil and
monitored the oil's performance via oil analysis.
Both oils' shear strength and TBN retention ability were examined
using ASTM testing procedures. The subject truck maintained
its usual operating procedure throughout the test period,
and the same driver operated the truck on the same route the
entire time. AMSOIL used the oil analysis results from the
initial drain interval, the subsequent drain interval and
a thorough teardown and inspection by an independent, certified
International mechanic to evaluate the performance of AMSOIL
Synthetic 15W-40 Diesel and Marine Oil.
The Navistar DT466
engine employs a hydraulically actuated, electronically controlled
unit injector (HEUI) system that uses engine oil pressure
to run the fuel injectors. The HEUI system was designed to
produce lower combustion noise and reduce hydrocarbon and
nitrous oxide levels during combustion, offering quieter,
cleaner diesel engine operation. HEUI systems feature a variable
pump (in addition to the oil pump) that pressurizes the oil
according to the fuel injection system's needs, placing a
considerable amount of additional strain on engine oil. HEUI
systems can raise oil pressure to as much as 3,500 psi, creating
great potential for shearing and adding significant stress
to motor oil that is already operating in a severe environment.
The HEUI system's reputation for shearing less robust motor
oils made the DT466 engine the perfect choice for testing
the durability of AMSOIL
Heavy Duty Diesel and Marine Oil.
983-HOUR DRAIN INTERVAL
Wear metal levels
were tracked through oil analysis for the duration of the
drain interval. As the results reveal, AMSOIL Diesel Oil contained
wear metals well below International's published condemnation
limits, even after more than 900 hours of use.
1 displays the accumulation of copper wear particles
in AMSOIL Synthetic Diesel and Marine Oil over 983 hours.
Due to the extreme environment created by the HEUI system,
the condemning limit for copper levels in the DT466 engine
is 60 parts per million (ppm). Even after 983 hours of use,
AMSOIL 15W-40 Synthetic Diesel and Marine Oil contained only
7 ppm of copper. The HEUI system's tendency to cause oil shearing
thins out lesser oils at normal operating temperatures and
increases the likelihood for abnormal engine wear. As the
results demonstrate, AMSOIL Synthetic 15W-40 Diesel Oil provided
outstanding shear stability for the duration of the 983-hour
2 charts the rate at which iron wear particles
developed. Once again, the extraordinary demand the engine's
HEUI system places on engine oil results in a low condemnation
limit of 200 ppm of iron. Even after 983 hours of use, AMSOIL
15W-40 Synthetic Diesel and Marine Oil contained less
than 100 ppm of iron.
3 details the accumulation of lead particles
over the drain interval. The condemnation limit for lead content
is 60 ppm. A sudden spike in lead levels or levels that approach
the condemning limit indicate an abnormal wear situation and
can indicate the need to drain the oil. AMSOIL 15W-40 Synthetic
Diesel and Marine Oil maintained consistently low lead levels
throughout the 983-hour drain interval, never going above
15W-40 Diesel and Marine Oil maintained exceptional lubrication
properties for the duration of the 983-hour drain interval.
It maintained viscosity better than Shell Rotella T did, measuring
12.33 centistokes (cSt) when drained. Shell Rotella T, on
the other hand, measured 10.17 cSt after its 239-hour oil
drain interval. AMSOIL Diesel Oil demonstrated superior shear
stability over an extended drain interval, even in severe
4 shows kinematic viscosity of Shell Rotella
T and AMSOIL Diesel and Marine Oil for the duration of their
respective drain intervals. The trend line for a high quality
motor oil should remain relatively flat for the entire service
period. AMSOIL 15W-40 Synthetic Diesel and Marine Oil shows
a stable trend over the extended service period, well beyond
the OEM recommended drain interval.
An oil's ability
to maintain corrosion protection throughout its service life
is measured by Total Base Number (TBN). AMSOIL Synthetic 15W-40
Diesel and Marine Oil is formulated with a high 12 TBN to
ensure corrosion protection from combustion blow-by and exhaust
gas recirculation (EGR) for the life of the oil. AMSOIL Diesel
Oil displayed excellent TBN retention ability for the entire
983-hour drain interval.
5 shows TBN results for AMSOIL Synthetic 15W-40
and Rotella T for the duration of their respective drain intervals.
TBN levels and hours of service have an inverse relationship;
as hours increase, TBN decreases. It is important that the
slope of the TBN line is gradual and spans the life of the
lubricant. A sharp downward trend indicated poor protection,
which, if not addressed, can result in piston deposits and
ring sticking. AMSOIL Diesel Oil's performance in the TBN
test is in line with how a high quality oil should perform.
It maintains TBN levels to effectively neutralize acidic by-products
of combustion and keep engine components free of deposits
ROUTINE ENGINE TEARDOWN
8,000 hours of use, Nordic Waste brought its International
7400 refuse hauler to certified International Truck mechanic
Dan Lee for a routine teardown. Lee, who specializes in the
DT466 engine, examined the pistons, rings, wrist pins and
bearings, while the top and bottom cylinder (bore) diameters
were measured by PDQ Engine and Machine in Duluth, Minnesota.
6 shows the subject truck's valvetrain. The
valvetrain is typically prone to varnish and sludge deposits
on non-moving parts and valve springs. Sludge and varnish
buildup appears as a thick, dark residue. Many times, sludge
is baked into a hard-to-remove carbonaceous consistency associated
with an engine lubricant being overloaded with insolubles.
AMSOL 15W-40 Synthetic Diesel and Marine Oil's robust additive
package and high TBN kept the DT466 cyclinder head and valvetrain
free of deposits and sludge.
7 shows one of the cylinder liners from the
DT466 in Nordic's truck. Lubrication is essential for the
bore to remain operational. If sufficient lubrication is not
provided, excess heat may cause thermal expansion, which can
force the cylinder out of round and significantly increase
the potential for wear. After nearly 8,000 hours of operation,
the OEM cross-hatch pattern in the cylinder is still evident,
demonstrating AMSOIL Diesel Oil's excellent wear control in
spite of the extreme shaking, jarring and revving the motor
is subjected to on a daily basis. Though it is slight, the
most wear occurred at the top dead center of piston movement,
where there is only light oil film lubrication. Figure
8 shows top and bottom bore measurements along
with the OEM specifications. Measurements for the sixth cylinder
were unavailable as International Truck retained that sample
for their records.
in this engine was representative of an engine that had accumulated
far fewer hours. In fact, Lee indicated that each piston was
suitable for continued use. AMSOIL Synthetic 15W-40 Diesel
and Marine Oil resisted oxidation and volatility to allow
minimal carbon deposit development between compression rings,
on the crown and inside the ring land area. Conventional lubricants
can allow unnecessary carbon buildup in these areas, which
can cause piston ring sticking and unnecessary wear. After
nearly 8,000 hours of service, the piston rings and skirts
in Nordic's truck measured within OEM specifications for a
new DT466 engine.
8 shows the top and intermediate piston ring
measurements. Piston rings are measured by determining the
gap in each ring. As piston rings experience wear, additional
room for ring expansion is created, widening the ring gap.
Lower measurements equate to less wear, yet any measurement
within OEM specifications is equivalent to rings when new.
All of the top piston rings were still within International
specification limits for new engines, with an average measurement
of 0.015 inches. All of the intermediate rings but one measured
0.074 inches, which is within International specifications.
Since all of the other rings had identical measurements, it
is possible that the ring that was out of specified limits
had been so since it was installed. Figure 9
shows ring locations.
10 shows Lee measuring a piston skirt in order
to determine the amount of wear that had occurred. Skirt measurements
are determined by measuring the outer diameter of the piston,
halfway between the crown (top) and base. The diameters of
each piston skirt from Nordic's truck were identical, measuring
4.585 inches (see Figure 8). The
piston skirts showed no measurable wear and were within International
specifications for a new DT466 engine.
11 shows an example of the piston skirt and
crown from Nordic's DT466. Lee indicated that piston cleanliness
was similar to engines that had accumulated significantly
less hours and were suitable for continued use. None of the
pistons showed any signs of abnormal or visual wear.
12 shows one of the wrist pins from Nordic's
truck. Extreme force in the combustion chamber transfers the
load directly to the wrist pin, creating the need for a durable,
shear stable oil in order to prohibit metal-to-metal contact.
The wrist pins from the Nordic Waste truck measured within
OEM specifications. No flat spotting occurred and, even after
daily severe service over extended drain intervals, the wrist
pins' measurements were similar to when originally pressed
into the piston by the engine manufacturer. (See Figure
8 for measurements.) Higher measurements equate
to less wear because as wear occurs, wrist pin diameters are
reduced. AMSOIL 15W-40 Synthetic Diesel and Marine Oil's superior
film strength delivered exceptional protection in this severe
environment, effectively preventing component wear.
13 shows the bearings from Nordic's DT466 engine.
No copper lining or discoloration was evident on the bearings,
proving that very little wear occurred. They were very clean
and showed insignificant levels of pitting in the bearing
surface. According to Lee, each bearing was in good condition
and showed wear levels consistent with those of a light-duty
engine receiving four times as many oil changes.
of copper showing on the bearings proves minimal wear has
occurred," said Lee. "For the hours on this unit,
these bearings look very good. If it weren't for the routine
maintenance interval requiring replacement, these bearings
are still in good enough condition to be reused." Lee
attributed the minor wear on the bearings to break-in wear
when the engine was new. "What little wear was evident
on the bearings was from engine break-in and the bearings
look far better than many I have seen," said Lee. Engine
bearings cannot be measured without the piston rods and end
caps, which were put back into the motor prior to Lee's inspection.
USE OF AMSOIL DIESEL OIL SAVES
Experience With Conventional Oils
Between the unique
climate and geographic challenges, the HEUI system, constant
use of the truck's hydraulic applications and regular near
redline operation, Nordic Waste's trucks provide a serious
challenge for any motor oil. In fact, it was Nordic's search
for an oil that could withstand the punishment doled out by
its vehicles every day that led the company to AMSOIL.
big hills, high heat and extreme cold we work in, nothing
has performed better," said Nordic Waste Owner Brian
Johnson. Johnson noted that Nordic Waste had installed other
diesel oils in its trucks, including Shell Rotella T, but
none were able to provide the level of protection offered
by AMSOIL Diesel Oil. Prior to discovering AMSOIL, the conventional
lubricants Nordic used would shear out of viscosity grade
rapidly and need to be changed at approximately 200 hours
of service. Upon switching to AMSOIL
Synthetic 15W-40 Diesel and Marine Oil, Nordic Waste increased
the average drain interval for its trucks from approximately
200 hours to nearly 1,000 hours.
The extreme temperatures
faced in the Duluth/Superior region place great strain on
Nordic's fleet. Winter temperatures dropping below -30 degrees
F are not unusual, so cold starts and hydraulic functions
are especially sensitive areas for Nordic Waste.
were a primary concern for us," said Johnson. "Even
though we use block heaters in the winter, you never know
when you might come to work and find that the breaker tripped
or a driver forgot to plug in the truck the previous evening."
Nordic's drivers begin their day around 3:30 a.m., so there
is no time for troubleshooting or engine repairs prior to
beginning their routes. The cold start issues plagued Nordic
Waste for nearly six months out of every year, until the company
switched to AMSOIL products.
lubricants, when trucks weren't plugged in, starting would
be difficult, if even possible, and even if the trucks turned
over, engine protection would be minimal because no oil pressure
would appear on the gauge," said Johnson. The test truck's
operator, Wayne Carlson, noticed the difference with AMSOIL
Diesel Oil right away. "The truck has excellent performance
in winter," said Carlson. "It fires right up without
being plugged in and there is instant oil pressure with AMSOIL.
In trucks I have driven using conventional lubricants, it
could take more than a minute to build any oil pressure when
cold, providing little engine protection." AMSOIL Synthetic
15W-40 Diesel and Marine Oil is formulated to provide exceptional
cold temperature performance. Its cold flow properties have
saved Nordic Waste time and money, and delivered peace of
mind with the knowledge that the company's trucks will start
on even the coldest winter morning.
Diesel Oil Saves Money
Use of AMSOIL
Synthetic 15W-40 Diesel and Marine Oil, along with oil
analysis, has allowed Nordic Waste to extend its trucks' oil
drain intervals to nearly 1,000 hours - four times the length
of service possible when using Shell Rotella T. Nordic's trucks
are well protected and experience optimum fuel economy, so
they stay out of the shop and on the road.
less downtime and have seen reductions in costs associated
with engine overhauls and replacements parts," said Johnson.
Refuse haulers are very expensive, so maintaining spare trucks
is not affordable for a small company. Operating with a minimal
number of trucks requires maximum uptime to ensure customers
are serviced properly. By delivering superior protection over
extended drain intervals and improving engine reliability,
AMSOIL Synthetic Diesel and Marine Oil provides Nordic Waste
consistent dependability and reduced maintenance (increased
uptime). Increased uptime has helped Nordic Waste maintain
an accurate schedule and provide excellent customer service
- trucks are more readily available for routes when they aren't
in the shop for service. In addition to improving the company's
operations, extended drain intervals save Nordic a considerable
amount of money annually.
"We buy significantly
less oil, fewer filters and we experience lower labor costs,"
said Johnson. "Our biggest savings have been the reduced
number of engine overhauls and replacement parts."
Use of AMSOIL Synthetic
15W-40 Diesel and Marine Oil saves Nordic Waste thousands
of dollars in oil alone, in addition to reduced expenses for
labor, filters and waste oil and used filter disposal. Figure
14 shows the annual savings realized by converting
one truck to AMSOIL
Synthetic Diesel and Marine Oil. AMSOIL Diesel and Marine
Oil is installed in all 10 of Nordic Waste's trucks, providing
an annual savings of $3,963.60* in oil costs alone.
Use of AMSOIL
Synthetic 15W-40 Diesel and Marine Oil helps Nordic Waste
reduce its environmental impact, something that's important
to a company that provides recycling services. Nordic's extended
drain intervals have reduced the amount of oil the company
disposes of by up to 75 percent. In addition, AMSOIL Diesel
Oil's superior thermal resistance helps it effectively resist
volatilization (burn-off) better than conventional oils. "This
truck hardly ever consumes oil; less than one quart per oil
change, which is very good compared to oils in other trucks
I have driven," said Carlson.
15W-40 Diesel and Marine Oil provides superior performance
in the harsh environment faced by refuse haulers. Through
oil analysis, Nordic Waste has been able to safely extend
the oil drain intervals in the company's fleet to more than
four times the drain intervals possible using Shell Rotella
T. In this field study, AMSOIL Diesel Oil demonstrated excellent
wear protection for the entire 983 hour drain interval. Its
TBN retention was excellent, it provided exceptional corrosion
protection and minimized sludge formation, as evidenced by
the absence of corrosive areas or sludge buildup on engine
components during the routine teardown. AMSOIL Synthetic Diesel
and Marine Oil prevented soot thickening, resisted oxidation
and minimized wear. It also maintained proper viscosity for
the duration of the 983 hour drain interval in spite of the
severe operating environment and HEUI injection system. Adversely,
Shell Rotella T 15W-40 sheared out of viscosity grade rapidly,
requiring an oil change after only 239 hours of service. Nordic
Waste's use of AMSOIL
Synthetic 15W-40 Diesel and Marine Oil has improved the
fleet's performance and longevity, and reduced the company's
maintenance costs. AMSOIL Diesel Oil saves Nordic Waste a
significant amount of money annually.

are often overlooked as a way to improve efficiency and minimize
costs, use of AMSOIL
5W-40 Synthetic Premium Diesel Oil (DEO) over conventional
15W-40 oils presents fleets with an effective way to reign
in costs without sacrificing protection. In fact, industry
tests demonstrate a 1 percent fuel economy improvement by
switching to 5W-40 diesel oil, while the Environmental Protection
Agency's (EPA) Federal Test Procedure confirms that AMSOIL
5W-40 Synthetic Diesel Oil provides up to 3 percent better
fuel economy than conventional 15W-40 diesel oils (1.6 percent
improvement at a mix of 55/45 city/highway driving).
For example, a
single truck traveling an average of 120,000 miles per year
and receiving an average of six miles per gallon consumes
20,000 gallons of fuel a year. At a price of $3 a gallon,
annual fuel costs for this single truck are $60,000. By switching
from a conventional 15W-40 diesel oil to AMSOIL
5W-40 Synthetic Premium Diesel Oil and achieving a 1.6
percent fuel economy improvement, the truck reduces its annual
fuel usage by 320 gallons, saving $960. The savings mount
when extended to larger vehicle fleets. A 50-vehicle fleet
saves $48,000 in fuel costs, while a 100-vehicle fleet saves
AMSOIL 5W-40 Synthetic Diesel
Oil Offers Maximum Viscosity Protection
Hard working diesel
engines present a serious challenge to the lubricants that
protect them. Tight clearances and intense pressures can generate
enough force to tear apart the molecular structure of the
oil, causing permanent viscosity loss. Permanent viscosity
loss is termed "shear" and leads to accelerated
equipment wear and oil consumption.
measures a lubricant's ability to withstand shear forces without
degrading to a lower viscosity. To meet CJ-4 requirements
for shear stability, the American Petroleum Institute (API)
requires diesel oils to pass the Kurt Orbahn 90-Cycle Shear
and maintaining protective viscosity in the harsh operating
conditions of diesel engines is challenge enough for many
diesel oils, but maintaining viscosity in the face of fuel
dilution is another challenge altogether. Factors such as
frequent starts, excessive engine idling, short trips and
cold weather have contributed to moderate levels of fuel dilution
in diesel applications for years, while recent issues with
emission systems have brought the fuel dilution problem to
a whole new level. (read

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.

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,

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 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
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

to have to pump several pumps, with brand X grease, before
the grease started squeezing out. Now when he starts to pump

covered a two-year period and the vehicle accumulated 212,326
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. (read

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

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

Efficiency Air Filters - Nano Fiber Technology
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
75W-90 Synthetic Gear Lube using the L-37 High Torque
Axle Test and the L-42 High Speed Axle Test. (read
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
What is the NOACK Volatility
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.
Quality Takes Priority at AMSOIL
The AMSOIL chemical laboratory
plays an important role in the daily operations at AMSOIL
headquarters. The lab fulfills tech service requests, performs
competitor testing and comparisons, and works on the research
and development of products at AMSOIL. One of the most important
jobs at the lab is quality control. AMSOIL is known for formulating
high-quality products and the AMSOIL chemists ensure that
everything coming in and going out meets AMSOIL standards.

Fuel Dilution Surfaces as Issue
in Some Modern Diesel Engines
AMSOIL has documented
two separate fuel dilution issues in modern diesel applications,
one of which has forced the company to reduce its drain interval
recommendations in a few applications using AMSOIL
Premium CJ-4 Synthetic Diesel Oils (DEO, DME). AMSOIL
recently released a technical service bulletin detailing that
fuel dilution issue and providing updated recommendations
for AMSOIL Premium Diesel Oils. (read
AMSOIL has documented
increasing levels of fuel contamination (fuel dilution) in
the engine oil of 2007-2008 light-duty Ford, GM and Dodge
diesel pickups, and indications are that 2009-2010 models
are also affected. Research indicates fuel dilution is intensifying
due to the use of in-cylinder post-fuel injection during the
engine's exhaust stroke to regenerate the diesel particulate
filter (DPF). Fuel in the oil reduces the oil's life expectancy
and effectiveness. Because diesel fuel is a natural solvent,
fuel dilution in motor oil causes a decrease in viscosity
which may lead to an increase in engine wear rates.
Premium Diesel Oils have shown the ability to maintain integrity
under fuel dilution conditions, the abnormally high rate and
unknown long-term effects have forced AMSOIL to adjust its
drain interval recommendations as a precautionary measure
in 2007-2010 Dodge 6.7L, Ford 6.4L and GM 6.6L LMM light-duty
turbo-diesel pickups. In these applications, AMSOIL recommends
changing AMSOIL Premium API CJ-4 Synthetic Diesel Oils (DEO,
DME) at the manufacturer-recommended drain interval. Drain
intervals may be extended further with oil analysis.
announced a fuel dilution issue in 2007-2009 on-highway Caterpillar
C13 and C15 engines that forced the company to adjust its
drain interval recommendation in those applications to the
manufacturer-recommended drain interval.
In all other applications,
AMSOIL full synthetic diesel oils are recommended for three
times (3X) the OEM recommendation, not to exceed 50,000 miles/600
hours or one year, whichever comes first, while Synthetic
Blend 15W-40 Heavy Duty Diesel and Gasoline Motor Oil (PCO)
is recommended for the longest OEM recommended drain interval.
Drain intervals may be extended further with oil analysis.
Synthetic Motor Oils offer the longest drain intervals
on the market, unsurpassed protection and performance that
effectively extends equipment life and improved fuel economy,
saving customers money at the pump and reducing the nation's
dependence on foreign oil.

company's recommendations and instructions."
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.
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.
NOACK Volatility Test
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
