I have heard that injector cleaning and use of a gasoline additive can help increase fuel mileage, is this so?
Yes, fuel additives help prevent carbon buildup inside the combustion chamber, and on the back face of the valves. These rob the engine of power, which means less gas mileage. So clean the injectors or use a gasoline additive that keeps the injectors clean, will help clean off the carbon and that will improve engine efficiency, which will means better gasoline mileage for you going down the road.
