Three Tiers of Amsoil Quality
Choose Your Drain Interval
- Gasoline Engines
Amsoil has three tiers of motor oils for light truck and car applications. You may choose your drain interval between one year, six months or oem drain intervals.
- Diesel Oils
Amsoil has a complete line of diesel oils for semi-trucks, light duty pickups, tractors, etc. The lineup includes diesel oils for both Model Year 2007 and new plus pre-2007 diesel engines.
- Break-In Oil
Amsoil's Break-in SAE 30 viscosity-grade oil formulated without friction modifiers to allow for quick and efficient piston ring seating in new and rebuilt high-performance and racing engines. Contains anti-wear additives to protect cam lobes, lifters and rockers during the critical break-in period when wear rates are highest, while increased film strength protects rod and main bearings from damage. The primary goal during engine break-in is to seat the rings against the cylinder wall.

Provides extra protection for flat-tappet cams, lifters, rockers and other areas susceptible to wear. Unique blend of rust and corrosion inhibitors ensure maximum protection during long-term storage.
- Dominator® Series Synthetic Racing Oils

and high-performance applications. Shear-stable formulation ensures critical engine
components are protected for the duration of the race. Effectively reduces friction for
maximum power and cooler engine temperatures, resulting in improved lap times and
