Gasoline contains detergent additives. Isnt this enough to prevent deposits?
A2. In many cases the detergents in gasoline can reduce or prevent deposit formation. Sometimes, changing brands or grades of gasoline can be beneficial in reducing deposit formation if driveability problems are encountered. In other cases the detergents in gasoline are not sufficient to prevent deposit formation. Unfortunately, there is no way to tell if a vehicle is prone to deposit formation. To prevent driveability problems and maximize fuel economy many technicians recommend periodic fuel system cleaning.
