Re: Oil Level
I also tried some 0 weight Royal Purple oil in my LT-1 EFI Firebird...for one race weekend....
Mostly what I saw was oil pressure dropping lower than I cared for at low engine rpm. I Dumped that oil after 1 race and went back to Mobil 1 5-30 that worked well and was faster than any oil I used before....and maintained good pressure.
I used pretty std oil pumps in the Stockers I had....
Neither car was fast but both easily ran below their indexes without spending a fortune....
