with the 5W-40, you'll get the same cold start protection and your engine should sound the same upon startup. it'll just protect better once it runs operating temperature. the mobil 1 5W-40 runs close to the same thickness as GC 0W-30 at operating temperatures. though the oil base isn't as exotic, it's surely better than mobil 1 5W-30.
mobil 1 10W-30 will keep your engine noise the same once the oil heats up as 5W-30 and 10W-30 would be the same thickness and protect the same once operating temperatures are achieved, so skip right over mobil 1 10W-30.

anthony i do not want the same protection as GC.. you see that is what my motor sound so wierd.. i honestly might do the 10w30 and 15w50
like you said in the pm.. my ls1 might like the thin oil??

M1 5W-30 often produces high wear numbers. GC 0W-30 is known to be loud at startup but after it warms up it SHOULD fade. i would say go 5W-40, it'll work even better for you. i was joking about your LS1 liking a thinner oil, that's unusual as hell. maybe you got a bad batch of GC? who knows.
I will then try the M1 5W40.. i will see how that plays out with me on my next oil change... I might have been protectin, but to someone who does not know a lot about cars they prolly thought i had a fvcke dup motor or something.. it was loud... can barely hear the valve train noise now with the M1 5W30... Very weird i tells ya
