I once tried RP very thin oil in my Firebird Stocker.

Oil pressure would drop to near zero at low engine rpms...

I Dumped that oil out after 1 race weekend.....and it was no faster than what I was using before.....Mobil 1 10-30 or 5-30.....and oil pressure was always good with the Mobil 1 and it was faster than most other typical oils.....
