Normal oil pressure

Your right. I forgot about the back flow valve.

Yeah either that or you'll throw a rod lol

I know!! Sounds crazy to me but that was there suggestion.

I had the same experience as BLU BY U, my pressure after the first oil change (~500 miles) dropped to just above the first tick from previously being just under 30.

An interesting thing happened today. My oil pressure went up to just under 30 today again. The only thing I did differently was rev the motor to 5000 rpm for the first time (not really intending to). Anyone else see this pattern? I thought maybe a valve in the filter (AC PF48) or engine bypass may have been stuck.

Have you had the chance to get a proper diagnosis by a dealership? I would recommend going this route since you may have a warranty on the vehicle.

I dont like anything below 40, especially in a brand new car.
I dont know if its the synthetic or by design but it bugs me everytime I see how low it is.
but your readings are on par with what Im used to in mine

yea me too......40-60 warmed is what im used to...idle to WOT

They have a oil pumps that drop way down at idle and under light loads all the way to 10 psi or less. Its to save gas oil plumps take a lot of power to move that much oil at high pressure.

this will take getting use too....i see the 25 and about

looking that way here too......takes a bit to get use too.....

thanks for this thread guys

Yes.

I think that was the reason I first joined Camaro5. The V6 pressure is always high. Pinned when you first start her up.

Normal at idle when fully warmed up!

I noticed just yesterday when first started up it was almost at 60psi and too me a little by surprise. After warming up though, it sat 29-31.

Reading this easied my concerns a little.

Mine reads in "Bar" like 3.1 bar at idle

Nope. L99 here and it's just about the same.

cold oil flows thicker...more psi.

Gosh i remember stuffing ky or grease in oil pumps to get a prime on a rebuild

Hmmm...I remember chucking an old distributor shaft in the engine, attaching an electric drill and spinning the oil pump to push oil thru the engine. Pull the old distributor shaft, put in distributor, adjust basic timing and fire the engine.

That is actually much higher than the others in this thread have reported (about 45 psi).

[Mack-SS]

Hmmm... Just thought I would check this forum to see what others are showing for PSI because I just changed my oil (Mobile1 synthetic) with the recommended 8 qts for a 2013 2ss and my PSI is almost maxed out when I rev the engine. This look bad? I drove about a mile today and the PSI was almost all the way to the right on the gauge. Is there a sensor that might warn me if the PSI is too high?

[CamaroTom]

I have never seen my gauge read that low at idle. My hot oil pressure at idle is 28-29 psi since day 1.
