Exceptional Cold Weather Shifting

AMSOIL Long-Life Synthetic SAE 50 Transmission Oil’s -46C pour point allows for smooth and easy shifting on even the coldest mornings. Oil reaches vital components instantly in all weather which contributes to long transmission life.

Synthetic Transmission ProtectionAMSOIL SAE 50 Long-Life Synthetic Transmission Oil Shows Minimal Wear

AMSOIL’s robust synthetic formula is designed to not only improve shifting performance; it is also designed to prevent wear after long intervals of extreme heat and heavy loads. After a half million miles of service using AMSOIL SAE 50, the transmission in the images shown (left) was torn down and its parts were measured. The input drive gear and output shaft bearing showed minimal wear. AMSOIL’s shear-stable synthetic base oil delivers long lasting film strength protection.

Prevents Leaks For Years to Come

AMSOIL Long-Life Synthetic SAE 50 Transmission Oil conditions all types of seal materials which curbs leaks over long periods. This is another vital feature toward maintaining long-term transmission health.

Mixing AMSOIL SAE 50 Long-Life Synthetic Transmission Oil with Other Brands

AMSOIL SAE 50 Long-Life Synthetic Transmission Oil is compatible with other brands of conventional, semi-synthetic and synthetic automatic transmission fluid. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities.

The use of any aftermarket oil additives with this AMSOIL product is definitely NOT recommended.
