i went with the 0w-30 Signature series amsoil.
Mobile 1 was the worst rated synthetic out of them all... kinda surprised me because i used to run it in my other race cars before i switched to Amsoil

Whats bad about M1 5W-30 is that its a thin 30 weight. The best way I can explain it it that German Castrol for example is a 0W 39 lets say, M1 would be a 5W 31, still a 30 weight, just thinner. LS motors prefer a thick 30 weight. M1 0W 40 is a thin 40 weight so it works well.

Some of you have no clue what the hell you are talking about. There used to be an awesome post about oil somewhere on this site. But I am sure it is gone and buried now.

Don't beleive all the crap you read on the internet. Amsoil is an exellent choice I know people that use it and they get great results from it. Penzoil I don't know about yet. There conventional oil is garbage maybe there synthetic is better.
There is nothing wrong with Mobil 1, ive been running 5w-30 in my LS1 since it was new and it just hit 181K miles. Doesn't smoke or tick and lights the tires up upon request.
