Anybody know what the oil pressure range should be at, like at idle and at some RPM's?

98 XJ with 150,000 miles

oops, I forgot to say it has a 4.0 sixer!

 

Well, my '91 (after lettin the oil warm up and get past that start-up pressure) it usually idles at about 25 psi and then during acceleration gets to a max of about 45 psi. This always seemed normal to me. What is yours normally doing?

 

mine warms up at about 60 and at running temp around 25 while driving its at 40 hope this helps oh mines a 90 with the 4.0 six

 

i have a 99 sport
its about 40 at idle,an 50-55 on acceleration
however i am running 1/2 quart high on purpose

 

i have an 01 with the six....startup and cruising speed, i have around 50-55psi...once warmed up and at idle, around 25-30
170k....maybe theres something to this mobil 1 oil after all!!!

 

lol... I get 20psi at 55mph and ~15 idle... one of these days I gotta get a mechanical and see if its right. (15w40 Valvoline Maxlife, 15w40 superduty diesel in 500 mi)

My girlfriends 96 runs ~60PSI at 70mph (10w30 Pennzoil HM)

 

my buddy's 01 runs diff pressure everytime he starts it he said i think its just an xj thing im told rhat 20psi is the normal for hi mileage xj's mines got over 200 on the clock and like i said in a prev post mine is around 20 at running temp at idle but 40 when driving and it makes no diff its at 45 or 65 its still the same

 

Idle and drive at about 40. When going around curves it drops a bit.

 

'99 4.0. drives at 50-60 psi, idles at 30-40 psi. a good rule of thumb is not to trust the stock oil pressure gauge too much. so i've heard.

 

I would assume it would help if everyone was saying what type and weight of oil they were using.

 

I have had an issue with mine that I have yet to be resolved too. Nothing has happened thus far but mine stays basically all the way at 80 90% of the time. I dont know why. When I accelerate it pegs the top. Not sure why.

 

sounds like a bad sender. ~20 for a new one, afaik.

 

"sounds like a bad sender. ~20 for a new one, afaik"

Was that in regards to the original poster or to my reply?

 

interesting range of pressures here.

At idle I get about 25 and with a little throttle I hit about 50 ish but spend plenty of time in the 40's

Just thought I would ask to make sure that isn;t some sort of issue I need to look at.

Thanks for the great response!
