hi

i have a 97 k2500 suburban. the oil pressure is always around 40 - 45 psi when idling and around 60 - 65 psi while driving. is that normal? I think it is a little high! or can I just leave it like it is?

Thank you

If I remember correctly, that sounds like where my '96 ran. My '04 doesn't show quite as much variation. Good Luck!

My 93 runs lower at idle. What weight/brand of oil are you running?

You might want to try 10-30w. Haynes manual specs that for the temp range you'd be operating in.

My 97 subs oil pressure runs about the same, that is not to high it shows the bottom end is in good shape. I have run 5-30 winter and 20-50 towing in the summer the gauge reads the same max pressure once warmed, the 20-50 will show about 10 higher at cold idle.

Ok, I live in the Desert and we got an average temperature in the winter around 70°F and in summer 100 - 120 °F. So I'm probably not too bad with 10-40 I guess.
