8.2% More MPG with AMSOIL
Replacing popular conventional engine
and driveline lubricants with AMSOIL synthetic lubricants
in Class 8 diesel-fueled vehicles increases fuel mileage up
to 8.2% according to the findings of an independent test facility.
Fuel accounts for roughly 37
percent of Class 8 truck operating expenses, and reducing
fuel expenses is a top priority for truck operators.
AMSOIL is the leader in the
race to develop fuel efficient low-viscosity lubricants for
trucking and other heavy-duty diesel applications. Independent
laboratory testing shows AMSOIL Series 3000 Synthetic 5W-30
Heavy Duty Diesel Oil in the engine and AMSOIL synthetics
in the drivetrain provide up to 8.2 percent more miles-per-gallon
than other popular lubricants provide.
At the request of AMSOIL INC., an independent
research institute conducted a month-long test com-paring
the fuel consumption of Class 8 diesel trucks equipped with
AMSOIL synthetic lubricants to Class 8 diesel trucks equipped
with conventional lubricants.
The research institute used
the SAE J1321 Joint TMC/SAE Fuel Consumption Test Procedure-Type
II, an industry standard test procedure for comparing in-service
fuel consumption of a vehicle operated under two conditions,
one with the control lubricants in place, the other with the
test lubricants in place.
Vehicles and Route
three test and one control vehicles were 1995 International
Model 9200 truck-tractors with Cummins M-11 engines (rated
at 350 hp at 1600 rpm), Fuller RTXF 14710B transmissions,
Eaton Model DS/RS 404 drive axles (3.90 ratio), 11R-24.5 low-profile
tires and new oil and air filters. All four vehicles had been
operated between 250,000 and 285,000 miles prior to the study.
The trucks were equipped with
auxiliary weigh fuel tanks and quick disconnect couplings
to facilitate accurate data gathering. Each truck pulled a
45-foot long flatbed trailer equipped with 11R-24.5 low-profile
tires and loaded with concrete blocks so that the gross vehicle
weight (GVW) of each vehicle was 75,550 ±100 lbs.
test route represented typical long-haul interstate highway
operations, with asphalt road surfaces and generally flat
terrain. The low traffic density route covered a total of
40 miles with a 20-mile southbound segment and the return
north-bound segment. Fuel consumption was measured separately
for each direction.
Lubricants and Fuels
The control lubricants were Shell Rotella
T 15W-40 for the engines, Quaker State SAE 90 for the transmissions
and Citco 85W-140 for the drive axles. The control truck used
the control lubricants for all driving segments and the test
trucks used the control lubricants for their baseline segments.
The test lubricants were AMSOIL
Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil for
the engines, AMSOIL
Series 2000 Synthetic 20W-50 Racing Oil for the transmissions
Series 2000 Synthetic 75W-90 Gear Lube for the drive axles.
The test vehicles used the test lubricants for their test
All vehicles used Exxon No.

test vehicle ran a baseline segment, in which the truck was
equipped with the control lubricants, and three test segments,
in which it was equipped with test lubricants. The control
vehicle concurrently ran each driving segment using control
Conditions including speed,
tire pressure, headlight and fan use and window openings were
held constant between all vehicles in each driving segment.
Finally, testing proceeded only if wind direction, wind speed
and temperature were within test parameters.
The weight of fuel consumed by each
test vehicle and the weight of fuel consumed by the control
vehicle in each driving segment were used to determine the
percentage of fuel saved and the percentage fuel efficiency
improvement obtained by the test lubricants. Results outside
2 percent of the norm were discarded.
The vehicles equipped with
AMSOIL synthetic lubricants in the engines, transmissions
and drive axles demonstrated up to an 8.2 percent increase
in miles per gallon (mpg) over the mpg obtained by the vehicles
equipped with the control lubricants.
conditions were held close to ideal for maximum fuel economy.
In many instances of less-than-ideal conditions, the synthetic
test lubricants would have provided even more fuel economy
improvement. For example, synthetics' superior cold temperature
fluidity provides a larger proportion of fuel savings in cold
Additionally, while the present
study did not include analysis of wear control, wear control
is an important issue with low viscosity lubricants and one
fully addressed by AMSOIL through additional testing.
Traditionally, the benefit of
improved fuel economy provided by low viscosity lubricants
is offset by a penalty in wear control. Such is not the case
with Series 2000 and 3000 lubricants, as evidenced by Four-Ball
Wear testing conducted by an independent laboratory (results
shown on product labels) and a growing body of demonstration
and on-road data.
example, an ongoing fleet demonstration is providing evidence
of the excellent wear control of Series 3000. Since January
1996, AMSOIL and a northern tier trucking fleet have been
conducting a demonstration using Series 3000 in the 1996 Cummins
N-14 ESP3 engines of five 1996 Kenworth class 8 trucks.
The trucks traveled 125,000
miles with-out an oil change and the rate of wear metal generation
found in used Series 3000 samples was lower than that found
in used control oil, Pennzoil Long Life 15W-40, which is changed
at 20,000-mile intervals.
Additionally, the viscometrics
of the AMSOIL fluids provide a wear control benefit in cold
temperature applications since low viscosity fluids flow more
freely in cold temperatures than high viscosity fluids do.
Oils that flow easily in cold temperatures provide faster
post-startup wear protection in cold engines than do less
fluid oils. They also provide easier starting and reduced
Finally, AMSOIL product users
are protected by the AMSOIL warranty, which, unlike warranties
offered by other oil companies, is not limited by time or
mileage and does not require user registration and approval.
AMSOIL synthetic engine, transmission
and drive axle lubricants provide a safe and effective means
to significantly increase class 8 truck fuel economy.
AMSOIL Series 3000 Synthetic
5W-30 Heavy Duty Diesel Motor Oil provides better wear protection
than these popular high viscosity diesel oils. In fact, independent
testing showed the high-viscosity oils tested produced wear
scars up to 45 percent larger than that of Series 3000.
What Does a Savings of 8.2%
Imagine a fleet of 100 class 8 vehicles
running an average 120,000 miles per year at an average 6.5
mpg with diesel fuel at $1.35 a gallon. The fleet spends $2,492,308
on fuel annually. Now imagine the fleet uses AMSOIL products
and improves its miles-per-gallon by 8.2 percent. The fleet
now spends $2,303,427 on fuel annually.
That's a savings of
$188,881! That money could buy a year's worth of
AMSOIL synthetic lubricants for the fleet plus a year's fuel
for 3 to 6 trucks - with cash left over!

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.

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.

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

better than other motor oils. AMSOIL Synthetic Motor
