At the moment, I am using Castrol 20W/50, and I am happy with it. I don't think I am making the jump to synthetic because of some implications, but wold like to know if I will need to increase my viscosity or is 20W/50 just fine to continue to use?

Some sort of M-3 envy going on here....

I've used both M-1 0W-40 and GC 0W-30...and felt that they are both "too thick" for the SVT. 5W-30 (or either M-1 0W-20 or 0W-30) would be the ticket for our cars..
