Frequently Asked Questions

These fuel additives are referred to as “clean up” products and will dissolve harmful deposits that may have accumulated in your fuel system (including fuel injectors, intake valves and the carburetor). These are all sensitive parts of the fuel system that control the fuel/air mixture and must remain deposit-free in order to work properly. By removing deposits in your fuel system, you can restore your vehicle to its optimum performance level, help maximize fuel efficiency, decrease hard starts, restore lost acceleration and decrease rough idling.
