My truck's oil pressure is running high. I checked the oil level and it is not overfilled, in fact it could be topped off a little. I changed the oil a few months ago, the pressure has stayed high the entire time.

What could cause high pressure?
The needle is on 60. The highest number on the gauge is 80. I always heard it is best for it to run in the middle, which would be 40.

If the pressure is running at 60 I wouldn't worry about it. You may have just changed to a better grade of oil. It's better to have oil pressure that is high than pressure that is to low.

Pull the oil pressure sensor and put a pressure gauge into the threaded orifice and test the pressure.
Maybe it's a bad sending unit?
