Hello JeepGarge forum... Could anyone tell me what the reason could be for my oil pressure to be running high in my 2002 jeep grand cherokee 4x4?? When I first start the jeep the gauge goes all the way to H. When I am driving it stays there but when I am stopped it goes down the the 3/4 mark. The check engine light is not on. There is no other engine noise out of the ordinary, plenty of oil & "normal" oil drips, normal running temps.
I committed a sin & deviated from my normal oil & tried to use a "supposedly better" oil, Valvoline Max life. I didn't like how the jeep "felt" & drove. I noticed this 2 days ago & am pretty good at keeping an eye on my gauges. I thought that since this has never happened before, it must be the Valvoline oil. I did a oil change yesterday, going back to my normal oil and it is still doing it.
I'm thinking it is an oil pressure switch has gone bad, but any other thoughts?
