  The oil pressure specification for your engine is 13 PSI at idle hot, 37 to 75 PSI at engine RPM higher than 1600. I suspect your oil pressure gauge sender unit or gauge is inaccurate. (High oil pressure could be a stuck oil pressure relief valve). I would have a known accurate mechanical oil pressure gauge temporarily screwed into the present oil sender unit to verify actual pressure.

• Oil pressure
  My wrangler oil gauge use to read in the middle of the gauge. Now it is pegged out on the high end. Everything else seem fine. Oil is full and is running fine.

• Gas in oil?
  I noticed my oil was almost a quart high, then I noticed the smell! Would this be piston rings of fuel pressure problem? 85,000 miles on odom.
