I have a 1995 Jeep Cherokee, straight 6, 4.0L that usually reads high for oil pressure, even when the level of oil is right. It is usually 3/4 of the way high on the dial, whether its hot or cold, new or old oil. It sometimes goes down a little bit when it's pretty warm and I'm on the highway. What does this mean?
I didn't ask the original question, but perhaps you can help. Thanks!
