Does Sea Foam clean oil pressure sensor on a Chevy Silverado? [SOLVED] Asked by Timothy K. In Michigan Does Sea Foam Motor Treatment also clean the oil pressure sensor screen in my 2013 Chevy Silverado 5.3?
Oil screens on Chevys with active fuel management have a tendency to gum up and cause low pressure readings. When added to oil, Sea Foam Motor Treatment (or better yet, High Mileage Motor Treatment) will clean anywhere the oil flows in the crankcase. Try adding 1 oz of High Mileage for each quart of oil in the crankcase.
