I have a 2000 XJ I had the oil changed recently to a 5w-30 and then took it to the cliffs for some off roading fun..


Got back and I noticed my oil pressure is really really high it stays at 80 from the second I turn the vehicle on till the second I turn it off the only time it comes down is when I come to a stop light and put the vehicle in neutral also noticed that the temperature gauge is sitting higher too at around 210-215. Normally oil pressure will be at 40 when stopped and about 60 when I accelerate. Tonight I am changing the oil sending unit to a new one and also changing the thermostat to a 180 hoping that it fixes the problem if not what else could it be and how can I fix it? Thank you

The oil pressure sending unit is most likely bad. I’m fairly confident that your problem will be solved once you swap it out for a new one. Sometimes they just need to be cleaned.

I took the road less traveled. Now I'm LOST.

Thanks y'all turned out to be a combination of the mud and the oil sending unit
