Driven Racing Oil, born from Joe Gibbs Racing, is formulated specifically for all-out race and high performance engines. These products are formulated specifically for racing engines and older style flat-tappet engines. Racing engines see more RPM, higher loads and increased temperatures compared to street engines, so a racing engine requires higher levels of Zinc, Phosphorus, Sulfur and other additives to prevent premature part failure. This is especially true in flat-tappet engines. Driven Racing Oil contains all of the correct additives, like Zinc, Phosphorus and Sulfur in addition to the highest quality base oils to protect your engine. A recent addition to the line of Driven products are items designed specifically for the newer street engines like the late model street Ford Modular engines, Chrysler's Hemi, the LS Series engines from GM and Harley Davidson Motorcycles.
