Question What is your oil pressure at idle?

What is your oil pressure at idle when your engine is warmed up? Mine is a little under 20 psi. Is this too low? I have a 95 Z with 5w-30 Moblie 1 synthetic. Thanks for any help.

With the oil fully warmed up and the transmission in drive, I see about 18psi on the gauge.

M6 cars should see a higher idle oil pressure since their idle speed is higher (800rpm vs 550 for the A4) Their oil pressure at idle should be closer to 30psi.

My M6 95 Z fully warmed up runs a little under 20 psi also. I think we are good.

96 LT1 M6 - 5w30 and when warmed up or hot, my pressure reads a little below 20.


20w50 for roadracing oil press reads a little above 20 at idle when warm/hot.

My M6, when it's all heated up, is about 35 or 38PSI @ idle.

The average idle PSI is 22 for most Lt1 F-bodys... 20 PSI is fine.
