We all like to look after our car, sometimes it's the things we think least about that can do the most damage. Ideal for everything from high performance engines to the family sedan, Liqui-Moly's Fuel System Cleaner and Conditioner is a great product that is significantly more effective than most fuel injection cleaners. Designed to deeply clean stubborn carbon deposits and contaminants from the fuel system, injectors and valves, this cleaning product restores horsepower and reliability. Once cleaned, the formula works hard to protect everything from the tank to the combustion chamber leaving behind a thin layer of film protection to keep the system healthy for up to 10,000km. This product is suitable for petrol and diesel engines running both carburettors and fuel injection systems.
