Brad Penn is loaded with Zinc as well. Thats all I use in the racecars is BradPenn 20/50 and MobilOne full syn in my other vehicles... The green oil is great for gas or alky it doesnt get contaminated as easy and its the slipperiest stuff I have ever used.

I ran Pennzoil 25/50 Racing Oil this season. Good oil pressure (80 psi cold and 35 psi hot at 1000 RPM). I run Alcohol so I change after very weekend and, of course it is milky when I change it. The heat stayed down (150 in the box and 185 at the end of the run). I will stay with this oil next years as it's reasonably priced at NAPA.

Unless you have some old stock Rotella T oil it doesn't have all the zinc in it anymore. If you run flat tappets it is a must that you use something with the ZDDP in it or use an addative.
