AMSOIL High Performance Synthetic 20W-50 Motor Oil is specifically formulated to provide tough lubricating protection in the most demanding operations.  It is recommended for use is motorcycles, pickup trucks, recreational vehicles and other high-stress vehicles powered by gasoline or diesel engines. AMSOIL SAE 20W-50 High Performance Synthetic Motor Oil may be used in all motorcycle engines, including those with a wet clutch system, requiring an API CD, SG-CG or SH-CD oil.

Wear Protection

The AMSOIL High Performance Synthetic 20W-50 Motor Oil anti-wear additive package contains high levels of zinc and phosphorous for superior protection of cam lobes and other high-pressure parts.  In fact, AMSOIL High Performance Synthetic 20W-50 Motor Oil contains more zinc and phosphorous than most popular motorcycle manufacturer motor oils.

Some motorcycle transmissions and engines share an oil sump, so the engine oil also provides wear protection to the transmission gears.  AMSOIL High Performance Synthetic 20W-50 Motor Oil offers superior wear protection to transmission gears, which are often subjected to high surface pressure and rotation speed.  It also promotes proper wet clutch performance.

Friction Modifier Free

AMSOIL High Performance Synthetic 20W-50 Motor Oil contains no friction modifiers.

Diesel Formulated

AMSOIL High Performance Synthetic 20W-50 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.

Temperature and Performance
