Around 30 psi hot.

 

in my car it 50 to 60 psi, what's going on

 

If your oil pressure doesn't behave as you think it should you can always replace the oil sender behind your intake manifold. Your pressure should be high when cold and gradually come down a bit, and raise with rpms. 10 psi per 1000rpm is safe, but when hot the lowest my pressure falls is about 20psi. The thickness and type of oil could have something to do with it as well.

 

Im at about 40 at idle, when hot, with Mobil 1 10w30.

 

mine is about 15 at idle. I just used mobil 1 10w 30.I just replaced the oil presture sender. My was on top of the oil filter. Do i still have a problem.

 

no, my oil pressure is 20 hot, on a mechanical gauge, with 2500 miles on a new motor with 10w30. its normal.

 

thanks . IS 20 the first line

 

15 PSI is normal at idle for these cars when they are at operating temp, that's were i'm at. Under load, it's around 40ish.

Thanks

 

Hey all i just replaced my sending unit. and drove around for a while and the gauge droped to just above the red line again. What else can i do. Please help

 

Sounds like it's time for a new oil pump. How many miles are on the ol' girl?

 

The block was rebuilt and has 27k on it. I wnt for a drive and the gauge was fine. I think the gauge is massed up. what do u think

 

Install a manual test guage (pick one up from your local auto parts store), it's the only way to tell for sure. I'm not certain where to install the guage, I assume that you would pull out the sending unit and test it there. But find out for sure.

i think the oil presure gauge is screwed up.... it is always sitting up at around 60 psi ( top of gauge ) it doesnt move much either. im very confident that the engine is running fine, i would just like to all of the gauges functioning properly.
