Driven Break-In Oil. This unique petroleum oil provides optimum levels of Zinc and Phosphorus for flat tappet and aggressive roller valve trains, and the additive package promotes ring seal. Provides the maximum protection available for cams and lifters during initial break-in. Break it in right and enjoy the benefits later. The Joe Gibbs Driven BR break-in motor oil should be pre-heated to 180 degrees F before firing the engine for maximum protection and can be used for up to 2 hours of break-in/dyno time before changing to race oil.
Red Line Engine Oil Break-In Additive provides conventional motor oils with anti-wear additives like zinc and phosphorus (ZDDP) necessary to protect against camshaft and valve train damage on break-in.
