SAE 30 Break-In Oil

AMSOIL SAE 30 Break-In Oil allows quick and efficient piston ring seating and protection for new and rebuilt engines. Cam lobes, lifters and rockers are protected by anti-wear additives during the critical break-in period when wear rates are the highest. In addition, increased film strength protects rod and main bearings from damage. Formulated with no friction modifiers, AMSOIL Break-In Oil allows sharp peaks on newly honed cylinder walls to partially flatten. This results in a larger surface area for the ring face to seat against, while allowing the formation of a dynamic seal that increases horsepower, compression and torque. AMSOIL Break-In Oil is designed for high-performance and racing engines requiring SAE 30 oil.
