It cleans catalytic converters, oxygen sensors, fuel injectors, and cylinder heads, improving fuel economy and restoring engine power. Safe for gasoline, diesel, and hybrid engines, it helps pass emissions tests, clear check engine lights, and prolong catalytic converter life with easy, tool-free application. ## Description Cataclean is a patented EPA-approved complete engine, fuel, and exhaust system cleaner that reduces carbon build-up and also cleans your vehicle's oxygen sensors, fuel injectors, and cylinder heads. Cataclean does not alter fuel composition and is safe for gasoline, diesel, and hybrid engines. Testing at an independent emissions testing facility showed using Cataclean can lower your total hydrocarbon emissions (Performance results are dependent on driver habits and vehicle condition.) Use Cataclean to fix drivability issues such as power reduction, hesitation, and hard starts, as a pre-treatment before an emissions test or to extend the life of your vehicle. Use four times a year to help maintain proper engine operation and catalytic converter efficiency. One application may not clean an already unhealthy catalytic converter, but the recommended four times per year usage can restore a dirty catalytic converter, maintain a healthy catalytic converter and support a well-running engine. Features: Easy to use - simply pop, pour and go every 3 months Does not alter fuel composition and is safe for gasoline, diesel and Hybrid engines Restores Catalytic Converter, Oxygen Sensors, Fuel Injectors and cylinder heads Pass smog and emissions tests with confidence Cleans and maintains Deisel Particulate Filters (DPF) Reduces Hydrocarbon Emissions on Gas Motors by up to 50% Reduces carbon build-up Improves Fuel Efficiency and MPG Legal in all 50 states EPA Approved Patented Formula e85/Flex Fuel safe New COEX-HDPE bottle constructed for increased strength with no evaporation Review: It works ! - Good stuff. It smells like some cerozine or nail polish remover. But , it works. Would help if it comes with dose bottle or something to see how much you are putting in your car. Worth to buy. Fast shipping. Prompt response. Review: Least expensuve P0 420 Emissions fix to try first - Good size. I keep an old single dose container and fill it from the 3 liter jug to not overuse. lm going to use it twice a year to keep my 09 ranger emissions system going long as possible. Over 222,000 kms now. 2.3 double overhead cam. Scotty Kilmer said it was a good year for Ford Rangers. Which i agree. Only a possible faulty airbag module recall. Otherwise as good as can be with regular maintenance. If you see a 2009 2.3 duratec thats seems to be somewhat cared about it, a reliable choice. ## Features - PASS EMISSIONS TESTS WITH CONFIDENCE: Cataclean is specifically formulated to reduce carbon build-up and clean vital components like catalytic converters, injectors and oxygen sensors, helping your vehicle meet stringent smog and emissions standards.
