JamesHigdon Posted February 2, 2012 Author Report Share Posted February 2, 2012 Well, it was pretty much what I expected with some surprises. It's good to know the info about W filters, we've been running purolater filter for years and besides their air filters flowing better we see cleaner oil with their oil filters. We will be stocking the full line of Valvoline products plus cherry picking some of the Amsoil products for customers who wish to use that. Just fired up my 100k plus mile, decade old, .480 lift roller motor in my autox/drag race/tow vehicle/daily driver for the first time in 4 months (it's been busy!) and having only ever seen Valvoline 30wt and Lucas it started up like new, can't argue with that! Thanks for the input. Link to comment Share on other sites More sharing options...

Danielsen Motorsports Posted February 18, 2012 Report Share Posted February 18, 2012 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. Valvoline Racing Oil is a good oil but even their previous high standards have dropped over the years! Link to comment Share on other sites More sharing options...
