I used Joe Gibbs Driven LS30 in my Camaro a few years ago, and have no complaints about it. You can get specs on their oil if you e-mail them. I got a spec sheet for LS30 directly from Lake Speed Jr. I classify JGD as boutique oil up there with Redline, AMSoil, and Motul. They make some very stout oils that are very shear resistant.
