The problem in the car is that the oil injection sends significant unburned synthetic oil out the exhaust and it eventually clogs up the catalytic converters. A very expensive thing for the dealer since they must certify the emissions system for 100,000 miles. The engine itself loves the stuff. I have around 1200 hours in the plane on Mobile1.
