Buster;
I thought you had 0W30 or 5W30 Amsoil before switching to 0W20.
As far as the C5 Vette guy, the 250 I-6 in my 1977 pick-up truck works harder.
The lightest oil that the little engine has ever seen is 10W30, and more often than not 15W40 or SAE 30.
Sure the light weights have their place. Just not in anything I own.
