the oil gauge is reading very high at 80 but i know their is only 6 quarts of oil in the jeep. 1999 jeep grand Cherokee
Answer:
The reading is too high and is more than likely not accurate. The problem is most likely the oil pressure sending unit sending the gauge the wrong information. You need to check the pressure with an external gauge to see what it is really reading and find out for sure if the pressure is 80 or really less due to an improper reading. The gauge goes in where the oil pressure sender is. Remove the sensor and install a gauge in its place.
