55 psi cold idle
25-30 psi warm idle
on the autometer mech. gauge

With Castrol GTX 10w40, K&N HP2002, stock oil system.

 

mine's 16 @ hot idle with 10W30 castrol
it gets around 40ish when it's up there in the Rs, but i pay less attention to that than the track...

 

Sounds to me like a lot of you could be using a lighter oil and making a few free ponies.

What do you reccomend Rich?

 

I'd run 5W-30 or maybe even 5W-20 if I saw pressure as high as some of you are seeing. I prefer slightly loose clearances and a heavier oil for myself though.

This works for me,

 

It didn't for me.

 

Do what Shoebox said:

Mine runs at just below 20psi at hot idle.

 

This kinda old thread, but my oil pressure is 60 psi at cold and 60 psi at warm idle, doesn't matter if its cold or warm, its stabile. At WOT It reaches around 75-80psi. Is it normal?????
Yes I'm using HV Oil Pump with 6q Oil Pan.

 

was 40 cold then below 20 hot but changed the sensor (pain in the rear) now its 65 cold and 30 hot these are idle pressures ( stock 97 Lt-1 97,000miles)

 

That sounds like a bad gauge. There is no way the pressure should be the same hot as cold. Do you mean "warm"" when the water temp gauge is in the operating range or do you mean when the motor is fully warm? The water temp will reach operating temp very quickly. It takes up to an hour of street driving for the oil to reach a steady state. Cold oil temps mean next to nothing.

Wow It takes 1 hour ?? I never drive 1 hour except I stuck in traffic. Hmm I want to test this then. I'm pretty sure my oil pressure is always at 60psi at idle. But If it goes to 75-80psi at WOT this means my gauge is working right??

 

I am saying that if the oil pressure is 60pis cold and also 60psi fully warm, something is screwy. I suspect the gauge but I suppose it could be something else. What oil are you using?

Rich

 

I'd like to use a lighter oil, I'm currently using Mobil 1 5w-30 synthetic what would be my best bet to go with?

 

Some cars are diffrent on a cold cool day mine is above the first line which, I have been using synthetic forever on that car.
