Wear control - Our synthetic diesel motor oils have been proven to keep wear rates lower than conventional oils do. 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 Þlm does not develop.

Acid neutralization and soot control - our 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 - our synthetic diesel motor oils remain ßuid in low temperatures. Low temperature fluidity helps engines start in cold temperatures and ensures rapid cold temperature post-startup protection.

Chemical and physical stability - our 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 - our 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 how 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 indeÞnitely, using oil analysis as their guide to oil changes.
