Mission Accomplished Tire & Auto offers our clients in the O'Fallon area the BG Platinum™ Fuel System Service. This service solves the problem of decreased performance & fuel economy in vehicles due to rapid accumulations of heavy carbon deposits in modern gasoline direct injection engines. When performed at our O'Fallon automotive shop, a vehicle's fuel injectors, cylinders, and intake valves are cleaned. In addition to restoring performance and fuel efficiency, this service also can reduce vehicle emissions that are harmful to our beautiful O'Fallon and surrounding County communities.
