We recommend and use Mobil1 5W30 in all our race cars. The same oil they make for regular production cars, we use in our 1450hp drag race engines. It keeps our main bearings looking brand new.

GM Racing has used Mobil1 for a very long time. Many years ago, we may have tried something else, but it didn't work as well. A couple of our teams have used different oil due to sponsorships. However, those oils, I believe, are specialty products and blends you can't buy off the shelf. And they still don't out-perform the Mobil1. Mobil1 is the only oil that we've done any long-term testing with, and it performs perfectly.
