GC 0-30 doesn't carry the GM4718M spec designed for Corvette. Since off the shelf Mobil 1 5w30 does and is used by several high end road race teams, this might be a good choice for you.


Mobil 1 5w30 is good enough for 636HP in the LS9 in the ZR1.

I vote for 5w40.
Rotella T6 would be my first choice. With other HDEO 5W40's a second choice.

IMHO 0W40 Mobil 1 shears too much.

I have no experience with Redline, the HTHS VS: kinemetric viscosity looks favorable. And I am just parroting others regarding Redline.

Sounds like fun.
Be careful Sir.

Rickey.
