HOW MUCH OIL PRESSURE SHOULD 2011 5.3 CHEV SILVERADO HAVE
Warmed up like 20 lbs. at an idle, and 40 to 60 cruising down the highway. If you are having low readings on your gauge, there is a screen under the oil pressure sending unit that needs to come out and be cleaned. It gets gummed up stopping the oil flow to the sensor. Should replace the oil pressure sensor since it would be out anyway.
