Hi David, It does sound like hi pressure for oil, but, maybe it's OK. The Vortec's are different animals than the cast iron engines, so, as long as it's getting a positive readout, then that's good. I changed the sending unit, so, it's' not that. I've owned the truck since new so for the first 12 years I must have really never paid that much attention to the gauge. I also ran the code reader yesterday and no codes anywhere. Guess I'll live with it! ha. Thanks for the info on your truck's oil pressure. LBJ
