CATERHAM, I'm not sure I follow. Are you saying "0w-20 + 4718M = ok for a 5w-30 spec'd Vette"....?
I know that 4718M is the "Corvette Spec", but does that mean any (i.e., a lighter viscosity) 4718M approved oil is ok?
I'm sure it probably could be safely done for nerdy Vette drivers who drive conservatively like I do, but is there a reason why one would *want* to use 0W-20 in their Vette over a 5w- or 0w-30?
(Thanks in advance, I enjoy your posts)
