I am running Valvoline VR1 20W-50 Synthetic Racing Motor Oil, hard to find and not cheap.
about $10-12 a qt is what I see online
My buddy runs that in his modified dirt track car. Its actually green!I haven't used but I know a lot of motor builders an race shops swear by Brad Penn oil. Hell I've never seen the stuff tho
