Mine at idle when first started is around 70-80 depending on how cold it is, and once warmed up between 30 and 40. 120,000 miles.

Anything above Zero is a plus. 20 or more at idle, hot would be best to see. 10 or more if really, really hot, just had a workout, etc. 40 or more on the road at running speed.

mine runs at 30-40 when warm at idle. When really cold and while running at speed it sits usually around the 50-60 mark. My is a 00 with 115k on it.

when my xj is at operating temp and its hot outside, my pressure will be right around 13 at idle. When I first start it up, it will go almost all the way up. Cruising down the road it stays around 30 or so...mine has 170,000 I6
