CAM2 Blue Blood Racing Oil. It's a high zinc and high phospherous formulation. I run their full synthetic 0w30 in my crate motor Stocker, which I also bracket race -- combined for 55-58 races a year. I feel that the thinner oils are more consistent in the late rounds as they can't thin out like a heavy oil when you've gone through a lot of heat cycles.

CAM2 also makes 15w30 and 20w50 synthetic blends, and gear lube as well. You can order right off their website, cam2racing.com
