    Description

    Tune-Up In A Bottle. Red Line SI-1 Fuel System Cleaner is designed to increase power, fuel mileage and lower exhaust emissions by cleaning and lubricating your entire fuel system (including carburetor and injectors) allowing fuel to burn more efficiently for maximum power, fuel economy and fewer emissions.

    Easy To Use. Just pour one 15oz bottle directly into the fuel tank of your neglected vehicle for the most effective treatment. Use in smaller doses as routine maintenance because one 15oz bottle can treat up to 100 gallons of fuel.

    Application. Red Line SI-1 Complete Fuel System Cleaner is safe for use in all 1979-2024 Mustangs, including the LX, V6, GT, Bullitt, Mach 1, SVT Cobra, BOSS and Shelby GT500 models. Sold individually.

    Technical Note. Red Line Fuel Cleaner CAN NOT be shipped outside of the United States. It CAN ONLY be shipped using Ground service.
