I definitely run at 80 PSI when cold, even with 5w-50 oil. Only when very hot do I see the oil pressure drop below to about 45 or 50 PSI at idle (again, with 5w-50 oil). Most of the time I idle at around 60 PSI even when hot.

2006 2500hd 80 psi oil pressure always - Fixya

3.3L = Oil pressure should be 5 psi at idle and 30-80 psi at 3,000 rpm with engine at normal operating temperature. You see that there is a large "in spec" region for the 3,000 rpm range as listed. I would look for the pressure to be at the higher end of the scale and the idle pressure to be right in spec.

How much is too much oil pressure? | The H.A.M.B.

 · Too much oil pressure can pump a lot of oil into the heads that can't make its way back to the pan as fast as the pump can pump it back up. I wouldn't think you would have an issue at 60 PSI. I know in some set ups people restirct the oil that is going up into the heads to protect the bottom end.
