My g37 is a 2008 with 122,000 miles and I tested the oil pressure it was at 10 psi idle and 38 psi at 2k rpm. Is this too low? Can it be the gallery gasket?

Also i’m on 5w30 and the car was operating temperature

 

Mine is around 36-40: https://www.myg37.com/forums/audio-v...-pressure.html

I recall reading somewhere that it can dip down to 17 psi and that's still considered "ok"

 

10 PSI is definitely too low for Idle, i have a oil pressure gauge with the sensor through a sandwhich plate and reads 26-28 PSI at idle on 5W-40.

 

The pressure will vary with temperature. Once oil temps hit the 180-200F range, idle pressure is lower in the high teens, which appears to be fine.
