939 250 cummins oil pressure question

[hot rod deuce]

Any body know what the NHC 250's run for oil pressure? 8-10 seems low even for 650 RPM. Im going to go try a nice new gauge while I wait for an answer



Thanks
Tony

Manual said oil pressure must be at least 15 PSI. Mine goes past center line on the gauge even at idle. I think its either 30 or 60 psi on center line.
