I have a 94 XJ 4.0 auto and the oil pressure is uncomfortably high. It generally sits around 70psi at idle and around 80psi when driving. After driving for over 30-45 min it wil drop to 40psi at idle but is still almost 80 while driving. I was running bargain brand 10w-30 for a while and about a week ago I switched to rotella 10w-30. I have replaced the oil pressure sensor and yes I got the one for the gauge and not the dummy light. There are no oil leaks anywhere and doesn't seem to be any weepage but it's hard to tell for certain on such a dirty block. Any ideas on what might be causing this? Is this something I need to worry about or can I just leave it be?
