Engine Oil

Rock, Thanks for your comments.

OK, the consensus is to stay with oil that has a zinc compound in it. I switched over to Lucas oil this year as well. I agree that the cost of sythetic does not make it practical for my class. I stayed with the 20/50 grade and the oil pressure would vary from 40-50 psi pre race and 20 psi or so post race. Second question is would a thinner grade oil help. I have expierenced lifter failure twice recently, (80 runs between failures) both on the right bank. 2 & 4 cylinders. It made a mess of a lot of parts. Don't want to go through that again.

Thanks,
