AMSOIL Inc. says its new 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.
The product contains high levels of zinc and phosphorus additives designed to provide the anti‐wear protection required during this critical period.
