AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL The First in Synthetics® to do the best job protecting your engine.

Provides Superior Wear Protection

AMSOIL Synthetic 10W-40 Premium Protection Diesel Motor Oil is a high viscosity oil engineered to protect against metal-to-metal contact. It resists viscosity shear and is formulated with a heavy treatment of anti-wear additives for excellent protection of gears, bearings, cam lobes and other high-pressure components in engines and transmissions. AMSOIL Premium Protection Synthetic Motor Oil helps extend engine life.

Exceeds the Requirements of Wet Clutch Transmissions

AMSOIL Premium Protection Synthetic Motor Oil contains no friction modifiers, making it ideal for motorcycles, maintenance equipment and other wet clutch transmission applications. Formulated to prevent clutch glazing and slippage, it insures smooth clutch engagement and long term, dependable transmission operation. AMSOIL Synthetic 10W-40 Motor Oil reduces clutch wear for extended transmission life.

Resists Oxidation and High Temperature Breakdown

AMSOIL Premium Protection Synthetic Motor Oil overcomes the thermal deficiencies common to conventional petroleum oils. Volatilization (burn-off), oxidation and excessive deposit formation from high heat are greatly reduced. Viscosity thickening is controlled and engines run clean, promoting cooler operation and long engine life in air or liquid cooled engines.

Extends Drain Intervals in Gasoline and Diesel Engines

The superior AMSOIL synthetic base stock and additive technology exceeds the requirements of both gasoline and diesel engines. AMSOIL Premium Protection Motor Oil neutralizes acids, disperses soot and lasts longer in service than conventional oils.

AMSOIL User Testimonials

"I already noticed a substantial improvement in my engine performance in fairly cold weather (10-20 degrees). With the fleet Valvoline petroleum oil, my diesel would burn oil for about 10 minutes while everything was getting warmed up. With the Amsoil, it burns oil for about 15 seconds on cold mornings and then clears up. Also, the differential is not sluggish in the cold weather with the 75W-90 s2000 gear oil."
