Royal Purple 5w30 - No complaints, no noise, etc
Mobil 1 5w30 - Noisy on startup, worse when cold. More noisy all around
Mobil 1 0w40 European formula - 90% as bad as the 5w30
Castrol Edge 5w30 - Ok. Not NEARLY as loud as the mobil, but not as quiet as the RP either...
Castrol 0w30 - Seems to be as quiet as the RP, and the engine is just as smooth, and a LOT cheaper.. I'm using this currently.
I've used the Rotella 0w40 in my old LS1 cars, and had the best luck with it. Once I get some more miles on the GXP, I'll probably eventually switch to the Rotella. For right now, the 0w30 Castrol Syntec seems to work best for me...
Its either about: what type of oil, what type of tuner, or what kinda mods can I do.***Not to be a dick***
But I use Castrol Blend 5w-30
Valvoline is not bad either. Mobil 1 is a good oil, just not for my particular engine. Too much valvetrain noise at all times.
