What makes this oil different from regular street oil?
Racing oils contain high levels of anti-wear and friction reducing additives that the API won't allow in modern street car oils.
Joe Gibbs Racing Oil started from the following!!
Mark Cronquist and the Joe Gibbs Racing engine department continue to experience flat-tappet camshaft failures on the dyno and at the racetrack. Research begins to find the contributing causes. Use of API rated engine oil is found to be a contributing cause. Development contract is signed and R&D begins on Joe Gibbs Driven Racing Oil.
Joe Gibbs Driven Oil is formulated specifically for racing engines and older style flat-tappet engines. A recent camshaft company Technical Bulletin said it best, "Today's engine oil is just not the same as it used to be, thanks to the ever tightening environmental regulations."
Today's passenger car motor oils are formulated to be compatible with your street car's emission control equipment, and Federal EPA requirements have led to a reduction in formulated anti-wear chemistries like Zinc, Phosphorus and Sulfur in API rated engine oils. As a result, the oil you buy today is not the same as it was 10 years ago. While this is good for your street car, it is bad news for your racing engine.
As stated in the book Lubrication Fundamentals,"In heavily loaded applications, flat tappet cam followers operate on partial oil films at least part of the time. Lubricants with anti-wear additives are necessary if rapid wear and surface distress are to be avoided. The oil additive Zinc Dithiophosphate is to provide anti-wear activity for the camshaft and lifters.”
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.
Joe Gibbs 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.
