I think my oil pressure is too high.
when im in second gear right around 2000 rpms im almost at 80 psi.

it idles around 45 to 50


this just doesnt seem right. . . or is the OP gauge in the cherokees just a dummy gauge

parkerbabco

normal.. should be around 60 while driving idle should be around 40

jeep_guy3

whats an easy way to get it higher if it is at around 10 and 20 psi?

10/40 or 15/40 for winter, if that doesn't help, try 20/50 in summer.

you can run straight 30w, or a 15w40. how old is the jeep?

if your going off the factory guage the readings arnt accurate.....

jeep_guy3

haha it is an 85 with 204,000 miles it was running around 40-60 when i baught it in december and has recently dropped... i just put in some 20w50 and it made it a little higher, im not too worried about it right now it doesnt drop below 10 and sounds good no ticks or nothing

Fraser

You cannot say that unless you actually test the gauge against a mechanical. mine runs ~10-20 at idle, and the gauge is actually right

Fraser

these are still a tad thin if your running low oil pressure. itll run 10w, 15w, and 20w when the oil warms up.
