 Wear Protection

     The Amsoil High performance 20w50 Synthetic Motor Oil anti-wear additive package contains high levels of zinc and phosphorous for superior protection of cam lobes and other high pressure parts. Amsoil High Performance 20w50 Synthetic Motor Oil contains more zinc and phosphorous than most popular motorcycle manufacturer motor oils. Its superior anti-wear package offers superior wear protection. Amsoil High Performance 20w50 Synthetic Motor Oil leaves a wear scar up to 40% smaller than the scars left by other popular brands in the ASTM D4172 Four Ball Wear Test.

     Some motorcycle transmissions and engines share an oil sump, so the engine oil also provides wear protection to the transmission gears. Amsoil High Performance 20w50 Synthetic Motor Oil offer superior wear protection to transmission gears, which often are subjected to high surface pressure and rotation speed. It also promotes proper wet clutch performance.

Friction Modifier Free

     Amsoil High Performance 20w50 Synthetic Motor Oil contains no friction modifiers. The friction modifier free formulation of Amsoil High Performance 20w50 Synthetic Motor Oil ensures dependable starting, smooth running, good fuel efficiency, desirable stall speeds and clutch compatibility.

Diesel Formulated

     Amsoil High Performance 20w50 Synthetic Motor Oil contains a robust dispersant / detergent additive package, making it ideal for use in high-stress diesel engines. Its 12+ TBN ensures lasting protection against acid and soot in high-stress diesel applications. In fact, its dispersant / detergent additive package is a proven extended drain lubricant.

Temperature and Performance

     Amsoil High performance 20w50 Synthetic Motor Oil offers the superior protection and lubrication at high and low temperatures found in top quality synthetic oils. Its outstanding low temperature fluidity ensures easy cranking, dependable starting and fast post-startup protection. Its superior high temperature protection ensures the formulation of a clean, protective film of oil between working parts during high temperature, high stress operation.

     High temperature operations often lead to the thermal degradation and oxidation of conventional oils, which leads to the formation of deposits, sludge, and varnish. Amsoil High Performance 20w50 Synthetic Motor Oil withstands thermal degradation and oxidation at higher temperatures than conventional oils do, ensuring clean, dependable performance in high-stress, high temperature operations.

New Vehicles Under Warranty

     Amsoil High Performance 20w50 Synthetic Motor Oil will not void new vehicle warranties. New vehicle warranties specify the use of oils meeting specific API service classifications and SAE viscosity grades. Amsoil High Performance 20w50 Synthetic Motor Oil meets the current API and SAE requirements ( as labeled ) and are perfectly suited for use in any new vehicle stipulating those requirements.
