the stock oil pressure sending units on our cherokees aren't very accurate so i wouldn't stress about oil pressure too much, pretty much as long as you have some pressure (even its 15 psi) , mine used to sit around 30 or 40 and jump up some when i give it gas, now that i'm running royal purple for about a year and replaced my sending unit by the oil filter, its always above 60, even gets up to 75-80 when i'm on the throttle...i'm just saying i wouldn't worry about it to much, just keep your oil fresh and use the right weights and your oil pressure should be fine.

I have a '95 and after riding on the trail for a bit, it would be just above 0. I was running 10w-30 at the time. Now I run that in the winter and 20w-50 in the summer. Its quite normal for a lower reading when the oil is hot. Alot of people change their oil weight for that reason.
