It's all relative. If your car runs consistently at a certain level, it's probably okay. The best measurement is a mechanical oil pressure gauge to see how your system is running. From there, you can make adjustments to the oil pressure electric gauge (or at least know that your H setting is okay as is).
Another alternative is that your sending unit is bad and it's pegging the gauge.
Good luck with your diagnosis! /forums/images/icons/smile.gif
