Cleaning the fuel system

Over time, deposits form in the fuel. These can have a negative effect on the injection system or the fuel pump. In the worst case, the entire fuel system may even fail. 

To prevent this, we recommend cleaning the fuel system with one of our fuel additives, depending on the intended use: Gasoline Engine System Cleaner, Injection Cleaner or Carburetor and Valve Cleaner.
