Cataclean Catalytic Converter & Fuel System Cleaner (16 oz) - 3 Pack

Cataclean is a superior cleansing agent and does not alter the fuel, whether gasoline, flex, or diesel in any way. It is specifically designed and formulated to "detoxify" the internal components of the engine and clean the oxygen sensors and the catalytic converter, thus reducing the carbon footprint of your vehicle and improving overall performance. Cataclean is not a fuel additive, so it should not be added to your fuel as a gasoline or diesel "enhancement". It is only required every 3 months, not every time you fill your tank.
