My c5 i just picked up when i come to a stop and sit there drops down to about 30psi for the oil, i thought it was supposed to be around 40. I just want to make sure that this is not a problem because if it is id rather do something about it now

Thanks guys

Thats fine. Mine is at about 32 in the warm weather we've been seeing.

yeah thats cool mine sometimes drops to 25 in warm weather in traffic. As long as you see 40s/50s during high accelatration, your fine.

Damn, thats pretty high hot idle. I guess because the oil is so much thicket.

I see as low as 29psi after I give the car a good stretch, low comp motor, Mobil 1 10W30, at 220 degrees.

Some guys see as low as 8psi at hot idle!!!!! Now THATS a little scary to me.

8lbs at hot...OIL IS TOOOOO THIN!!!! (imo)

Great, i was a bit worried now , just hooked up my autometer oilpressure gauge for the first time and started the LS1 in my 67 Camaro, mine is steady at 30 psi to . Thought it was supposed to be 50 psi at idle

Patman

Automatics and manuals will have a different oil pressure at idle due to the automatic having a lower idle, so keep this in mind.

Mine has an idle oil pressure of 28-29 psi when the oil temperature is 200F. Mine is auto, but the idle has been raised by 100rpm via LS1 edit.

I'm running German Castrol 0w30, which is almost a 0w40.

Mine is not quite that low, but it does dip to about 35 and at cruising speeds it is around 45.
