Driven (formerly known as Joe Gibbs Racing Oil) is a high quality oil suited for racing applications. The BR40 oil is a conventional oil designed for initial break-in period. This is the oil that MSW uses on fresh M5x, S52, and S50US engines.
The same high Zinc and Phosphorus formula as Driven’s original break-in oil, now in SAE 10W-40 viscosity. Well suited for classic muscle car, European sports car and motorcycle engines. Ideal for flat tappet and aggressive roller valve trains, as well as Ethanol blended, pure Methanol and oxygenated race fuels. Does not require additional ZDDP additives. Good for dyno testing, one night of racing or up to 400 miles on the street. Viscosity typical of 10W-40.
