Hey guys, I'm getting my car tuned in about a month, built motor 9.5-1 compression, hellion single precision 76, return fuel system etc. Now I've put about 1600 miles on the new motor with break in oil, and I'm going to change out the oil, to regular oil before it hits the dyno.
What does everybody use the stock motorcraft 5w20 or is there something else I should use? The car will be tuned on 94 + meth, 80%meth 20water
Thanks!
