understands that diesel pickups put a great deal of
strain on engines, drive trains, and the products
that lubricate them. AMSOIL's line of products geared
toward the heavy duty needs of diesel pickup trucks
provides umatched protection for your truck. Not only
can AMSOIL reduce the wear and tear on your engines
and equipment, but also allow your truck to go for
incredibly long periods without the need to change
In 1972, AMSOIL INC. introduced
AMSOIL Synthetic 10W-40 Motor Oil and became the first
company in the world to market and manufacture an
American Petroleum Institute (API) rated synthetic
motor oil. In 1975, AMSOIL introduced a synthetic
diesel oil, and with it, coined the term "extended
Since then, AMSOIL synthetic diesel
oils have been used as extended drain lubricants in
transportation, equipment and stationary engine applications.
In every industry, they have proven effective in improving
engine durability and fuel economy. AMSOIL customers
report significant savings realized through reductions
in downtime, parts replacement, lubricant replacement,
lubricant disposal and fuel consumption. Fleet demonstrations
and independent testing confirm what AMSOIL customers
report: using AMSOIL synthetic diesel oils saves money.
AMSOIL synthetic diesel oils lubricate
and protect diesel engines better than conventional
Volatility - AMSOIL synthetic
diesel oils' volatility is exceptionally low which
keeps oil consumption rates low and inhibits oil thickening.
For example AMSOIL Synthetic 15W-40 Heavy Duty Diesel
and Marine Oil loses only 6 percent of its mass to
volatility in the Noack Volatility Test. Other popular
15W-40 oils lose as much as 13.96 percent.
Stability - The excellent thermal stability of
AMSOIL synthetic diesel oils helps keep oil oxidation
rates low, inhibits sludge formation and ensures proper
engine lubrication and protection. It is a critical
factor in safely extending oil drain intervals.
Oxidation Resistance - AMSOIL
synthetic diesel oils' outstanding oxidation resistance
keeps engines cleaner longer for efficient operation
and long life. Oxidation resistance is also a critical
factor in extended drain intervals.
Low Temperature Performance
- The cold temperature fluidity of AMSOIL synthetic
diesel oils enables cold engines to start easily,
protects cold engines from premature wear after engine
startup, promotes excellent cold temperature fuel
economy and eliminates or reduces the need for inventories
of seasonal oils.
Fully formulated motor oils contain
additives that perform functions the lubricating oil
basestocks alone can't perform. For example, detergent-alkalinity
additives inhibit the formation of deposits on hot
engine surfaces and neutralize acids. Dispersants
inhibit wear caused by soot and debris. Viscosity
index improvers give lubricants multi-grade viscosity.
Other additives inhibit lubricant oxidation, metal
oxidation, rust and foam or prevent component damage
when a full film of lubricant isn't present to prevent
AMSOIL synthetic diesel oils are
formulated with the highest quality additives available
to ensure proper lubrication and protection in extended
Wear Protection - Wear protection
is provided by the lubricating oil in areas where
a full lubricating film develops between moving parts,
such as the bearings. It is provided by anti-wear
additives in areas where a full film does not develop,
such as the valve train.
The Four Ball Wear Test (ASTM D4172B),
a test designed to measure the effectiveness of anti-wear
additive systems, shows AMSOIL Series 3000 Synthetic
5W-30 Heavy Duty Diesel Oil produced wear scars as
much as 39 percent smaller than those produced by
competing petroleum and synthetic diesel oils. That's
significantly better wear protection.
Shear Stability - Some VI
improvers break down in demanding operating conditions.
When an oil's VI improver breaks down or shears, the
oil no longer retains its intended viscosity over
its intended temperature range, rendering the oil
unable to protect the engine from premature wear in
AMSOIL synthetic diesel oils are
highly shear stable. Shear stability is especially
important for engines that operate at constant speed,
such as stationary engines, marine engines and farm
TBN and Detergent-Alkalinity
- AMSOIL synthetic diesel oils are formulated with
12 Total Base Number (TBN), a high value designed
to provide superior control of corrosion and high
temperature deposits in extended drain service. Most
conventional diesel oils' TBN equals 8.
AMSOIL synthetic diesel oils' highly
effective detergent-alkalinity additives help piston
crownlands and compression ring zones stay clean,
inhibit bore polishing and piston deposits, minimize
cylinder liner wear, minimize ring wear and breakage,
and help keep oil consumption rates low.
The ability of AMSOIL synthetic
diesel oils to maintain high TBN values sets these
oils apart as superior extended drain lubricants.
Dispersancy - Dispersants
control soot and other contaminants and inhibit the
formation of sludge and deposits on low temperature
areas, such as the piston skirts and adjacent areas.
Lasting control of soot, other contaminants
and low temperature deposits are an integral element
of AMSOIL synthetic diesel oils' extended drain capabilities.
Complete Protection - AMSOIL
synthetic diesel oils also contain antifoamants to
prevent persistent oil foaming, anti-rust agents to
inhibit rusting and anti-oxidants and metal deactivators,
both of which retard oxidation processes.
