Synthetic Motor Oil

AMSOIL synthetic diesel motor oils help decrease downtime and increase profits with better protection and less expense.

Wear Control

AMSOIL synthetic diesel motor oils have been proven to keep wear rates lower than conventional oils. Synthetic base stocks are tailored to reduce friction more effectively than conventional base stocks, which lowers wear rates and helps keep engine heat from climbing excessively. Outstanding quality antiwear additives protect surfaces from wear in conditions that prevent a full lubricating film from developing.

Acid Neutralization and Soot Control AMSOIL synthetic diesel motor oils are 12 Total Base Number (TBN) oils and are proven to neutralize acids and control corrosion for longer periods than conventional oils. The top-quality detergents responsible for long-term acid neutralization also inhibit deposit formation on hot engine surfaces. The highly effective dispersants in AMSOIL synthetic diesel motor oils control soot and other contaminants, providing long-lasting protection against wear and sludge formation.

Low Temperature Fluidity

AMSOIL synthetic diesel motor oils remain fluid in low temperatures. Low temperature fluidity helps engines start in cold temperatures and ensures rapid cold-temperature
post-startup protection.

Chemical and Physical Stability

AMSOIL synthetic diesel motor oils offer superior thermal, oxidative and shear stability. Thermal stability
allows them to work in high temperatures without undergoing molecular breakdown and consequently increasing oil consumption and starting the formation of sludge. Oxidative stability allows them to work in high temperatures without undergoing chemical changes leading
to oil thickening, loss of lubricating ability, and sludge and acid formation. Shear stability keeps them from falling out of viscosity grade and losing their ability to protect against metal-to-metal contact and wear in engine operating temperatures as a result of shear forces.

Fuel Economy

AMSOIL synthetic diesel motor oils have a low friction coefficient that improves fuel economy by reducing the loss of power to friction. Fuel economy increases of five percent are common with AMSOIL synthetic diesel motor oils.

Extended Drain Intervals

Fleet demonstrations show AMSOIL synthetic diesel motor oils protect engines more effectively for extended drain intervals than conventional oils do for conventional
drain intervals. Essentially, AMSOIL synthetic diesel motor oils protect engines better longer. Many truckers use AMSOIL synthetic diesel motor oils indefinitely, using oil analysis as their guide to oil changes.

Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil

AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, formulated for diesel and gasoline engine use, offers a combination of engine protection and fuel economy unmatched by other oils. Independent lab tests show Series 3000 outprotects other popular diesel oils – even 15W-40 grade oils - by a wide margin.

Series 3000 Improves Fuel Economy.

Testing performed by an independent facility showed that class 8 trucks with AMSOIL Series 3000 in the engines and AMSOIL synthetic lubricants in the drivetrains obtained up to 8.2 percent more mpg than matched trucks lubricated with conventional products.

It’s a Proven Long Drain Oil.

An ongoing Class 8 fleet demonstration shows Series 3000 used continuously for 80,000 miles offers better TBN and viscosity retention, soot control and wear prevention than does a popular conventional 15W-40 oil changed at 20,000-mile intervals.

Synthetic 15W-40 Heavy Duty Diesel and Marine Oil

AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil has been proven superior to conventional oils in fleet demonstrations and countless miles of over-the road use. AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil reduces wear rates, provides extended drain service and saves truckers significant money.

AMSOIL Diesel Fuel Additive Concentrate

AMSOIL Diesel Fuel Additive Concentrate maintains injector cleanliness, increases fuel system life, reduces exhaust emissions, stabilizes fuel and improves cold temperature fuel performance. It contains lubricity agents, corrosion inhibitors and anti-rust agents to reduce system wear. Its cleaning agents remove deposits and keep new ones from forming, which ensures injector cleanliness for superior power and fuel economy and reduced emissions. Wax crystal suppressants and deicing agents in AMSOIL Diesel Fuel Additive improve the fuel’s ability to flow in cold temperatures. Fuel with AMSOIL Diesel Fuel Additive flows at as much as 20°F colder than fuel without Diesel Fuel Additive. AMSOIL Diesel Fuel Additive also contains moisture inhibitors and other agents that stabilize stored fuel.

AMSOIL Cetane Boost

AMSOIL Cetane Boost increases cetane by three to seven numbers. It contains fuel cetane enhancers, which increase startability, combustion efficiency and power, and decrease engine knock, smoke and emissions. AMSOIL Diesel Fuel Additive Concentrate and Cetane Boost are compatible and may be mixed in the fuel tank. Both are alcohol-free for seal and component compatibility.

Dual Gard By-Pass Oil Filtration

The AMSOIL Dual Gard By-Pass Oil Filtration System treats oil to ultrafine filtration, which increases engine and oil life and enhances engine performance. AMSOIL Ea By-Pass Filter elements remove submicron sized particles, keeping oil analytically clean. Clean oil lubricates and cools efficiently because its coefficient of friction is low. It promotes superior piston ring seal, which improves compression and engine power,and reduces blow-by, oil consumption and fuel dilution. Oil lasts longest when clean, since its additives are not consumed by contaminant control. The Dual Gard system allows the installation of two AMSOIL Ea By-Pass Oil Filter elements, doubling the by-pass filter element change intervals. The system also makes room for a larger volume of lubricating oil, allowing the oil to run cooler and rest more. Both increaseoil durability.

Synthetic Gear Lubes

AMSOIL synthetic gear lubes keep differentials and EP gear-lube equipped transmissions running clean, protected and at top efficiency.

Load-Bearing and
Extreme Pressure Protection

AMSOIL synthetic gear lubes are formulated to protect gears operating in heavily loaded conditions, whether or not the gears operate with full film lubrication. Superior film strength and viscosity retention offer superior protection in full film regimes, while top-quality extreme pressure agents protect when a full lubricating film
does not separate gear surfaces.
The thermal durability of AMSOIL synthetic gear lubes ensures extreme pressure protection after extended exposure to extreme temperatures. The extreme pressure agents in conventional gear lubes sometimes lose their effectiveness after extended exposure to high temperatures, leaving gears vulnerable to metal-to-metal contact and wear.
