In a racing engine, with racing oil, the oil is meant to protect the moving metal parts in the engine during the event. This oil is usually dumped out after a weekend, or a race. It was never meant to stay in your crankcase for 4-6-12 months as a regular oil. If you want to use it, go for it. Me---- working in street driven engines for the past 40 years as a professional--- I simply know better.

I use it in my 2015 Jeep Grand Cherokee, my 67 Mustang, and my 67 Corvette. I am not aware of any issues regarding its use whatsoever.
