Instructions for use:
The cleaning process can be performed in two ways, either through the fuel tank or by filling the fuel filter. Cleaning through the fuel tank: The most optimal cleaning process is with a fuel quantity of about 10 liters. Pour the contents of the bottle into the fuel tank, start the engine and do a test drive. If possible, about 30 km of even highway driving. After the test drive, refuel until the tank is full. If there is a larger amount of fuel in the tank, the cleaning process will be slower and, if possible, do a longer test drive. Cleaning through the fuel filter: Take a new technically suitable fuel filter for your vehicle. Fill it with Diesel System Cleaner and install the filter. Pour the remaining contents of the bottle into the fuel tank. Air the system. Start the engine and let it run at different speeds for about 10 minutes. Maximum speed 2000 rpm.
