Regular use reduces emissions by up to 60%, improves fuel economy, restores engine performance, and helps prevent MOT failures. Suitable for petrol, diesel, and hybrid engines, it’s the essential quarterly maintenance additive for professionals who demand efficiency and reliability. ## Description Product Description Improves engine performance and improves fuel consumption Use Cataclean To help reduce exhaust emissions and fuel consumption If your car has failed its MOT test due to high emissions Remedy poor engine performance or if you have a clogged catalytic converter Help to maintain petrol, diesel and hybrid vehicles If your car has a P0135 / P0141 / P0401 / P0420 / P0430 Engine Code If your car has a rough running engine All benefit from regular use of Cataclean Over time, due to build-up of residue, gum & carbon, problems can occur in an engine's fuel & exhaust system, causing an increase in fuel consumption, a drop in performance & an increase in harmful exhaust emissions such as carbon monoxide & hydrocarbons which, in turn, damage the environment. These problems can occur in all vehicles but tend to occur in older vehicles, vehicles that are used for short journeys, in vehicles that are continually stopping & starting or where fuel quality is poor. CATACLEAN is a fuel additive and is not a fuel enhancer CATACLEAN should be added every 3 months…not every time you fill your tank CATACLEAN is a complete engine fuel and exhaust system cleaner CATACLEAN rapidly dissolves carbon, gum and resin and similar deposits in the fuel and exhaust system CATACLEAN cleans carbon deposits from catalytic converters and exhaust particulate filters CATACLEAN can help to reduce emissions, increase fuel economy and prevent engine part failures CATACLEAN has no adverse effects on a vehicles fuel and exhaust system and is fully insured. It is developed and manufactured in the UK How does Cataclean work? Cataclean is an extremely effective cleaner that will remove carbon, resin and gum build-up from the fuel and exhaust system. It is different to other fuel & exhaust system cleaners as it can clean post-combustion as well as pre-combustion, helping with problems such as catalytic converter issues, catalyst codes and EGR Valve issues. Performance and efficiency robbing carbon build-up occurs as a natural by-product of combustion, more severe issues happen when this is left to accumulate over time, such as: blocked catalytic converters, dirty sensors and engine management lights. Cataclean’s mechanism of action is to clean pre- and post-combustion, pre-combustion Cataclean is carried with the fuel - removing deposits as it passes over components like the fuel injectors and upon combustion, Cataclean creates an acidic vapour of carboxylic acids which will clean the exhaust system including oxygen sensors, EGR valve, catalytic converter and exhaust. Negative consequences of carbon build-up can be reduced MPG, poor performance and increased emissions. Here are some of the signs you could need Cataclean Increased exhaust emissions, failed MOT/NCT emissions, reduced performance, black/white smoke, rough running, lower fuel consumption, reduced power, engine management light Using Cataclean can prevent and cure these problems and ensure your engine runs better and lasts longer. The ultimate 8-in-1 product, Cataclean can clean Fuel Tank & Lines Fuel Injectors Combustion Chamber Valves Oxygen Sensors EGR (Exhaust Gas Recirculation) Valves Catalytic Converter Diesel/Petrol Particulate (DPF/PPF) Filter About Cataclean Safety Information Highly flammable liquid & vapour May be fatal if swallowed and enters airways Causes skin irritation. • Wear protective gloves/eye protection/face protection Causes serious eye irritation Keep away from heat/sparks/open flames/hot surfaces (no smoking) Take precautionary measures against static discharge Use only outdoors or in a well-ventilated area IF SWALLOWED: Immediately call a POISON CENTRE or Doctor.

Had a check engine light come on P0420 downstream sensor issue. Checked a few potential culprits none of them resolved it, looks like it could be the cat convertor. Used a couple of these and premium fuel for the last 4-5 months now, check engine light switched itself off this week, seems to have resolved the issue. Will continue to use one of these every 6 months or so now. Would suggest the same if you have had similar issues, my fords about to hit 200k miles now and these things help keep it on the road.

I have check engine light. Low air flow from egr. After more than 5 miles drive the check engine light is gone. **Q: hi can i use in my kia sedona 2.9 diesel 2005 model thank you** A: Yes. **Q: Can i use it for Mercedes e class 2012 diesel?** A: I didn't use it on that car but my mechanic believes it is suitable for any diesel engine car **Q: Is cataclean ok to use on petrol turbo engines?** A: Yes, as the turbo only increases air intake; also turbo will not even be running at max capacity whilst car is slow. The extra air intake will also help clean cat any way. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective *by D***O on 6 July 2026* Good stuff. Had a check engine light come on P0420 downstream sensor issue.
