Thanks for a quick reply. I was waiting for someone to point that out. I'm running Amsoil for now but cannot decide what I want to use next.

There is no "best" oil. If there was, there would be no reason for anyone to use something else and then only one oil would exist.
Anything that meets the GM standard in your OM will do just fine, unless you highly modify your car. There's probably only 1 out of 50 million who would ever drive their car enough to determine if one oil is better than another and I'd guess you're not that one.

Good ol' factory spec Mobil 1.
I actually do race and that's what I have used in my C4 (100k+ miles), C5 (40k miles), and C6 (88k miles). Regular oil reports from Blackstone concur with my assessment.
But honestly, as stated by everyone above and the other million posts, it doesn't matter. Use any synthetic that meets GM spec, which will be any Mobil, Valvoline, Castrol, Royal purple, AMsoil, Brad Penn, etc etc etc...

was running royal purple 5w-30, I think it was awesome oil! this is on my built ls2 h/c and nitrous. ran it for the last 9k miles, now I went with rotella t6 synthetic, gonna change it more often. was changing royal purple around 3k. I think the rotella will hold up to the heat a lot better since its 5w-40 and its heavy duty diesel oil, also fine for gasoline. everyone has their opinion but to me a cheaper but yet good oil being changed more regularly is way better than expensive oil being used longer between changes.

All of RedLine oils are a Ester based oil, and Motul's 300V and 8100 series are also Ester based. These are the only oils with that as a base stock and even with all of the additive packages that the other oils come with, can not match the strength and protection of those.

This link did not work for me, but this link is to a thread on the forum that may be the same info and is actual test data. It may surprise you but a ball wear test is much more credible to me than blind speculation.
