I have a 5.0 engine and was wondering what the oil pressure should be running at?

93 LX FiveO

my engine has over 170,000 miles

cold idle: 52 psi
hot idle 44 psi

cold 2k rpm's: 60+ psi
hot 2k rpm's: 50+ psi

the rule of thumb is 10 psi for every 1k rpm's

use an aftermarket gauge to monitor oil pressure, the stock gauge is like a grandfather clock.

Ya i have an aftermarket gauge when i start it, it runs at about 50 then when it warms up a little over 40 so it seems to be close to what yours is

mine 175,xxx miles cold idle 55 psi warm idle about 25 thinking my main or rod bearings are getting a little wore out

With those miles i would say your oil pressure is great.

I have 'round oh 300,000 miles on mine and she runs 60psi@ cold idle, 30psi @ warm idle ; 60psi @ 2000rpm warm or cold... How 'bout them FORDS!!!!
