Low oil pressure in my GMC Envoy Denali [SOLVED]

A year ago my truck had a problem with low oil pressure when at a stop, so had to shift into neutral and step on the accelerator to increase the pressure. Everyone, including a GMC dealer, said just drive the truck till it quits. Then I tried adding a 1/2 can of Sea Foam to the oil it immediately took care of the problem. So now I add Sea Foam to my oil a week before every oil change to keep the filter screen from plugging up and slowing the flow. I also add it to my gas tank every 4th or 5th fill up. It works!!!!

Please pass this along to whoever at corporate so they know it cured one of my problems. What a great product it is!!!!!

My truck is a 2006 GMC Envoy Denali that has 240,000 mile on it and has the 5.3L engine.
