The oil pressure on my Grand Cherokee is pegged, 80 +, when it is cold and drops to about 60 - 65 when warm. It does the normal things likes increase when reved. Although I have never double checked the guage, I believe it is running high since I have had numerous problems with minor oil leaks. I have gone through 2 oil pressure valves that have leaked, and had problems with oil filters leaking. This problem has been going on for about 9 months. I have the oil changed every 5,000 miles, and it runs fine. It has about 120,000 miles.
