Oil Wt s & Brands?

[mbuskuhl]

I am running the Valvoline VR1 race oil, 20w-50, in my rx7. I change it every other race weekend.

+ 1.

Our Engine rebuilder recommended the lower viscosity to get oil to the Bearings more quickly on start up.

Consider an Accusump with manual valve. Mine releases 3qts at 80PSI (or wherever you close the valve at) into the system before start up every time. I assume you are also using the MFR bearings.
