Today on the way home from work on the freeway I noticed my oil pressure gauge had risen all the way to 80 so I pulled over and it fell back to the normal 40 where I usually notice it staying. Upon driving again it started to rise again. Dealership told me this was normal but I have never seen the gauge rise even when driving with the exception of one time after an oil change was performed at a local goodyear shop, it rose all the way to 80 on the way home. The shop told me to drain some of the oil cause they might have overfilled it! Thanks for the help!

While you are moving and at a steady speed does it fluciate? That is Does it go up and down while traveling at a steady speed or stay about the same? If it is constant when driving I would think it was normal.

The gauge has only ever risen like that one other time. A goodyear shop overfilled me on an oil change. When I drive the gauge always reads at the 12 o'clock position, it never climbs like it did today it always sits right on 40 no matter if I am driving or sitting still.

When you check the oil pressure what does it say when the engine is shut off? The guage should float just a little when the engine is running slow and should go up as the engine rpms increse.

When off the gauge is at 0 obviously. Once started the gauge climbs right up to 40 and stops. It sets at 40 constantly accept for the two occasions I mentioned. There is something I didnt think was related but would like to mention. Only when it is very cold out and never in summer my check gauges light beeps a few times right after the seat belt chime is done. You can check codes on a wrangler by turning the key on and off three times and no codes have come up. Also if you do the key thing and hold in the trip set button, it will go through the gauge cluster one at a time. All gauges/lights seem to be working with the exception of my 4wd part time and 4wd full time lights.
