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?
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.
