03 Silverado oil pressure
My Chevy 2500HD 6.0 liter has developed a problem. My oil pressure has always been 40 psi at idle and 50-55 psi on the freeway. Yesterday it started idling at 30-35 psi and 50-55 psi on the freeway....

I’ve seen sending units go bad on those. I’ve also seen the little screen underneath the sensor get plugged up from sludge. Are you changing the oil frequently or are you going by the oil life monitor which could potentially let oil changes go to 10k miles?
Either way you need to have the oil pressure physically checked with an actual gauge screwed into the oil pressure port.
