Oils for Superior Longevity and Profitability
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.
synthetic lubricants are superior to conventional
petroleum lubricants. Petroleum lubes are refined
from crude oil, a natural substance pumped from the
earth and containing diverse chemicals. Some of the
chemicals in petroleum oil are detrimental to the
lubrication process and to the lubricated components.
For example, some petroleum oil chemicals invite oxidation
in high temperature operations. Oxidation quickly
destroys lubricant integrity.
Synthetic lubes, on the other hand,
are not refined from crude oil, but constructed from
pure chemicals selected for their ability to lubricate.
The purity of synthetic lubricant basestocks significantly
reduces lubricant oxidation, which promotes the ability
of synthetics to be used in higher termperature applications
than conventional lubes may be and promotes their
ability to be used for extended drain intervals. In
fact, AMSOIL synthetic lubricants are specifically
formulated for extended drain intervals.
Synthetics are also free of the
paraffins found in conventional petroleum oils. With
no paraffin to congeal at low temperatures, synthetics
maintain better low temperature fluidity than petroleum
oils do, which protects equipment operating in cold
environments - even the relative cold of a just started
The molecular uniformity of carefully
selected synthetic lubes promotes superior lubrication
and friction reduction, which in turn promotes superior
heat control, wear control and energy efficiency.
Molecular uniformity also helps synthetics maintain
their protective viscosity in high temperature operations,
which also promotes superior wear control.
The superior performance and protection
afforded your equipment by AMSOIL synthetic lubricants
adds up to increased productive time and profits for
AMSOIL synthetic diesel oils lubricated
and protect diesel engines better than conventional
Volatility - AMSOIL synthetic
diesel oils' volatility is exceptionally low which
keeps oils 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
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
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.
synthetic diesel oils save diesel operators money
through increased fuel economy, increased engine durability,
reduced oil inventories and extended lubricant drain
Fuel Economy - Independent
testing and fleet demonstrations show engines equipped
with AMSOIL synthetic diesel oils operate with better
fuel economy than engines equipped with other diesel
oils do. Fuel mileage improvements in excess of three
percent have been documented in independent testing.
Engine Durability - Fleet
demonstration oil analyses comparing the performance
of AMSOIL synthetic diesel oils to competitive products
show lower rates of wear metal generation with AMSOIL
products. Engine part inspections confirm the outstanding
wear protection provided by AMSOIL synthetic diesel
oils. Lower rates of engine wear improve engine durability,
providing longer intervals until first engine teardown,
greater intervals between overhauls and longer engine
Oil Inventories - The outstanding
low temperature fluidity and high temperature protectiveness
of AMSOIL synthetic diesel oils eliminate the need
for special inventories of seasonal oils. AMSOIL synthetic
diesel oils are also formulated for use in gasoline
engines, to separate oils for diesel and gasoline
engines are also unnecessary.
Extended Drain Intervals
- AMSOIL synthetic diesel oils bear the Mack EO-M,Volvo
VDS and VDS 2 labels, showing they meet Volvo's demanding
extended drain performance results and the experiences
of owner-operators confirm that AMSOIL synthetic diesel
oils provide excellent extended drain service.
