hi im not getting a lot of oil pressure could you please tell me the norm im using millers oil

 

You could check the oil pressure wiring at the bottom of the engine, it is just behind the radiator fan. See if it is unplugged. IF it is...then I would not worry, the same thing happens on my Trooper. Just make sure your oil level is checked every week. My 98 Trooper has not had any issues with the oil pressure gauge being low.

If you are not aware yet, 98-2002 Trooper models are notorious in consuming oil due to bad engine design. See other posts for technical reasons behind it.
