What is Break In Oil?
Break In oils are essential to the long life of your newly rebuilt or crate engine. Driven Break In Oils are specifically formulated to protect new camshafts, lifters, pistons & cylinders and engine rotating assemblies from the initial wear that occurs during the first start up. Driven Break in oils are formulated to promote the final “wear in” of the new engine parts. Driven Break In Oils are formulated just for Break In and offer improvement over the Straight Weight, Monograde Non Detergent Oils of the past typically used for Break in.

How to Use
For best results, use this product for the first 30 mins of initial engine start up, drain and install a new filter. Then add New fresh DRIVEN GP-1 Conventional Break-In Motor Oil 20w-50 and run for 300-400 miles until the engine achieves break in. It is recommended you purchase enough break in oil for TWO oil changes. EXAMPLE your engine needs 6 quarts to fill, so purchase 12 quarts break in oil.
