Driven BR50 15W-50 (previously sold as BR) is a conventional petroleum break-in oil that provides optimum levels of zinc and phosphorus for flat tappet and aggressive roller valve trains. It typically carries 2800-3000 ppm of ZDDP with low detergent content, so it does not require additional ZDDP additives during break-in. BR50 is a break-in oil only and will not meet any current API or OEM engine oil specifications; after break-in the engine should be switched to a regular Driven racing oil.
