the oil pressure gage goes up half way when running and goes back to low during idling, anything wrong with my engine. I drive a 2004Tundra 4.6l V8 4WD Crew Cab
There is less oil pressure a idle than there is at higher rpm. Your pressure may be okay, but perhaps it should be checked with a mechanical gauge. Probably a good thing for a reputable mechanic to check out.
