So I finally got a real oil pressure gauge installed on my 1999 V8, but I am wondering what is normal PSI for the V8?

Mine is about 60PSI on startup, but goes as high as 80PSI when first driving. Down to 20 or so when hot and idling.

Sound normal or is that 80PSI too high? Wondering how accurate the gauge is or if there is something going on with the oil system (like a pressure relief valve sticking).

I have no frame of reference other than my other cars never go that high.

Thanks,

Kent

Btw, In case anyone is interested for future reference, my math (with about 14.5 psi per bar) puts that at...

20.3 psi at idle (about 1000 rpm)
34.8 psi at 3500 rpm
44.95 psi at 6500 rpm
