Cat Converter Cleaner

Catalytic converters are a key piece of technology fitted to modern vehicles designed to reduce exhaust emissions and have been mandatory on all petrol vehicles in the UK since 1993. Maintaining them effectively can save money and improve the efficiency of the engine.

How do catalytic converters work?

Catalytic converters convert harmful gases produced by the engine into less-harmful gases which can then be released into the atmosphere from the exhaust. These harmful gases pass through a chamber which contains a catalyst made of platinum, rhodium or palladium. These chemical reactions between gas and are either reduction or oxidation to remove oxygen from nitrogen oxide to form nitrogen and oxygen or to add oxygen to carbon monoxide to create carbon dioxide.

Catalytic Converter Problems

Over time, catalytic converters can clog due to carbon buildup. This can cause the engine to run inefficiently, using more petrol and losing engine performance too. MOTUL Catalytic Converter Cleaner is designed to dissolve resins, gums and carbon buildup around Lambda sensors and within the catalytic converter to restore the proper efficiency.

Recommended Use

Maintaining the efficiency, smooth running and performance of a petrol engine is not a one-bottle fix. Catalytic Converter Cleaner is recommended as part of the range of fuel system cleaners from MOTUL.

When cleaning a car or van, it is recommended to start at the top and work down. This makes sense, as spraying dirt from the bottom of the car upwards will create more work. Although it cannot be seen, the principle is the same when cleaning a fuel system.

Starting with the injectors, following with a clean of the fuel system and then preventing or removing clogging from the catalytic converter. Once this process has taken place, maintaining engine efficiency and reducing spontaneous combustion or preignition with an Octane Booster will maintain and extend the life of the fuel system.

Each fuel additive should be poured into the fuel tank prior to the car being fully filled with fuel.

Repeated use of fuel system cleaners and fuel performance boosters will provide the maximum efficiency and results.
