Curbs Oil Usage

AMSOIL 100% Synthetic High-Mileage Motor Oil offers a two-pronged defense against oil usage. First, the full-synthetic formula is highly resistant against volatility and boil-off when exposed to hot operating conditions. Second, the synthetic base oils deliver consistent shear stability and film strength. This robust film strength maintains consistent viscosity and prevents oil consumption.

Prevents Oil Leaks

AMSOIL fortified this High-Mileage formula with seal conditioners that help engine seals remain supple and resist drying out. This can prevent oil leaks from developing with age.

Note: This motor oil product cannot reverse pre-existing oil leak issues. 

Exceptional Wear Control

AMSOIL’s puts 50 years of synthetic wear protection know-how into this High-Mileage Series. Expect consistent wear control during extreme heat and under all driving conditions. This product is a cost-effective way to protect your investment.

Combats Power-Robbing Deposits

A major part of maintaining long-term efficiency and performance is preventing engine deposits. AMSOIL loaded this High-Mileage formula with powerful detergents to clean up deposits and prevent their formation.

Fast Cold-Start Protection

An important aspect of preserving an engine is providing quick oil supply to critical engine parts upon start-up. Every product in the AMSOIL 100% Synthetic High-Mileage Motor Oil line has a cold-pour-point that is at or below -44°F. This means fast oil delivery in all climates.
