Oil pressure please help

If you have 20 psi hot at idle and 30 psi hot on the highway with that 10-30, and it isn't knocking my guess is that you are fine.

Normal rule of thumb is 10 psi per 1000 rpm.

Figure your idle is around 750-850 rpm, 20 psi of oil pressure is more than enough.

More than likely you are under 3000 rpm at 60 mph so again, 30 psi of oil pressure is enough.


With that said, that 50 weight didn't do the engine any good.
