Quote from the Viper Service Manual, 1998:
"Oil pressure should be 10 psi at idle or 45-75psi at 3,000rpm". This is with a warm engine. I'm sure anything in that range is fine and nothing to be concerned about, even if it's constantly what some have called "high". My winter car in Massachusetts was a 1969 Olds Cutlass and had 6.......yes, SIX psi at idle and about 20-25psi all the rest of the time. The car ran for 175,000 miles before I gave it away, still running fine. Now, THAT is a loose engine! Ha! Pete the ex glass guy
