Wear control – AMSOIL synthetic diesel motor oils have been proven to keep wear rates lower than conventional oils do (see graph below). Synthetic basestocks reduce friction more effectively than conventional basestocks do, which lowers wear rates and helps keep engine heat from climbing excessively. Outstanding quality antiwear additives protect surfaces from wear in conditions in which a full lubricating film does not develop.

Acid neutralization and soot control – AMSOIL synthetic diesel motor oils are 12 Total Base Number (TBN) oils and have been proven to neutralize acids and control corrosion for longer periods than conventional oils do The top-quality detergents responsible for long-term acid neutralization also inhibit deposit formation on hot engine surfaces. AMSOIL synthetic diesel motor oils’ highly effective dispersants control soot and other contaminants for 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 with consequent increases in oil consumption and formation of sludge precursors. 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’ low coefficient of friction 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 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 oil by a wide margin. Series 3000 improves fuel economy. Testing performed by an independent facility showed that class 8trucks 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 fleet demonstration shows Series 3000 used continuously for 80,000 miles offers better TBN and viscosity retention, soot control and wear prevention than does 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 increases fuel economy, reduces wear rates, provides extended drain service and saves truckers significant money.

Semi-Synthetic 15W-40 Gasoline & Diesel Motor Oil

AMSOIL Semi-Synthetic Gasoline and Diesel Motor Oil offers the advantages of a synthetic at a more affordable price. AMSOIL Semi-Synthetic Gasoline and Diesel Motor Oil provides outstanding high and low temperature protection, thermal and oxidative stability and retention of TBN, dispersancy and viscosity. It is an ideal extended drain lubricant.

Synthetic SAE 30Diesel Motor Oil

AMSOIL Synthetic SAE 30 Diesel Motor Oil offers outstanding high and low temperature service and protection. Its low temperature fluidity is superior to that of conventional 15W-40 motor oils. Its shear stability, low volatility and high temperature film strength make it ideal for high-stress applications.
