What is one of the most important steps when finishing rebuilding an engine, breaking the engine in. Breaking in your engine will allow your engine to run properly and not break anything, and thanks to our Driven Break-in oil that will help you with it. Specifically designed for breaking in engines and flat tappet camshafts and lifters, BR break-in oil provides high levels of Zinc, Phosphorus and Sulfur in a mineral base oil. BR protects flat-tappet camshafts and lifters during break-in and it provides excellent ring seal. Combined with Joe Gibbs Driven Engine Assembly Grease, BR provides the highest levels of protection for camshafts, lifters, wrist pins, distributor gears, push rods and valve retainers. BR is fully formulated and requires no EOS or other additives.
