Description
Engine break-in is critical for establishing proper ring seal and wear patterns in a fresh or rebuilt engine. Comp Cams’ break-in oil delivers elevated zinc and phosphorus levels that protect cam lobes and lifters during this vulnerable startup phase—protection you won’t find in standard street oils. This conventional 10W30 formula is engineered specifically for high-load break-in conditions, ensuring your engine foundation is solid before you push it to the limit.
