Comp Cams Oils

Break-In Oil


Using an “off-the-shelf” brand of oil during the critical break-in process can lead to a failure.

COMP Cams engine break-in oil is designed for engine builders and performance hobbyists who want that added extra protection in order to maintain engine safety and performance.

The engineers at COMP Cams and Endure Performance Lubricants have been working hand-in-hand to develop a full line of automotive lubricants, the first being the ZZDP-enhanced engine break-in oil that provides maximum protection during initial engine break-in. This advanced lubricant provides maximum engine life, while also allowing the engine to reach its full performance potential.

This Break-In Oil consists of special blend of extreme pressure additives no longer available in off the shelf motor oils. COMP Cams engine break-in oil’s proprietary formula includes the optimum amount of critical additives like ZDDP (zinc and phosphorus), molybdenum, detergents, and high-grade base oil. The multi-viscosity, mineral-based COMP Cams engine break-in oil is fully formulated and requires no additives or supplements.
