Cataclean claims to lower the total hydrocarbon emissions by up to 50%, clean the entire fuel system all in for once and help the overall performance of the car. That is done thanks to the formula of the cataclean that enters from the fuel system to the fuel injectors, inside the combustion chamber and out to the exhaust. All the chains will be cleaned by using this product, furthermore, Cataclean can also clean your O2 sensors and carbon deposits, which will make for a car that runs more efficiently,
