What is break-in oil and why do I need it?

Break-in oil is specifically formulated to protect new or rebuilt engines during their initial operation. It contains additives like zinc and phosphorus that help the engine's internal components properly seat and wear in together. Regular motor oils often lack these additives due to government regulations, making break-in oil a necessity for engine longevity.

Can I mix this break-in oil with other types of oil?

Yes, COMP Cams Engine Break-In Oil is compatible with any petroleum, synthetic, or blended motor oil. However, it is designed to be used during the break-in period, so it's best to use it as the primary oil during this time.

Does this oil require any additional additives or supplements?

No, this break-in oil is formulated to provide maximum protection without the need for any additional additives or supplements. It contains an optimal amount of ZDDP, Molybdenum, and detergents to protect your engine during the break-in process.
