I have a 1999 Jeep Grand Cherokee Laredo. I recently had the oil changed. I noticed on my trip up to the Poconos this weekend that the oil gauge appeared pinned to max at 80. It pretty much stayed there throughout the trip.
I just checked it again after it sat for a few days. Gauges on, engine not running, it read 70, engine at idle, cold, it appeared just below 80.
Manual says normal is 20-70, tolerate as low as 13. It says nothing about if it is high. I am driving her to Vermont this weekend... is this something I need to have looked at before I go? What could go wrong if the pressure is too high? Also... I have her in center city and my regular mechanic is at the Shore, so if I need to get her checked its going to be a PITA unless someone has a good rec.
