The Valvoline EasyGDI Fuel System Service removes carbon deposits from hard-to-reach intake valves, piston tops, cylinder heads and fuel injectors in gasoline direct injection (GDI) engines. The service features an intake cleaner, fuel rail cleaner and a complete fuel system treatment. The system's technology allows 10 detergents to melt away carbon deposits and circulate to clean a GDI fuel system without having to dismantle the engine and fuel system. The results can include improved injector flow, improved fuel economy and power, and elimination of rough idle, hesitation and knocking.
