Removes deposits on injection nozzles and in the combustion chamber. Boosts the cetane number. Eliminates engine running problems such as knocking when idling and ensures smooth and quiet engine running. Protects the entire fuel system against corrosion. Optimizes the emission test values. Can also be used preventively. Clean engines use less fuel and reduce the pollutant emissions. Suitable for all diesel engines with and without a diesel particulate filter. As a preventative measure at each inspection, after repairs to the fuel system or for treating problems (see application description on the container). Tested for compatibility with turbochargers. Fully compatible with all conventional diesel and biodiesel fuels. Contents sufficient to treat up to 75 litres of fuel.


Preventive use: 

  • Add to diesel fuel according to the inspection intervals. 

Remedial use: 

  • Disconnect fuel feed and return lines and insert into the diesel purge. Start the engine. Run the engine at a variety of different speeds and switch off before the container is empty. Reconnect fuel lines to the fuel system and check for leaks. In cases of extreme contamination, repeat the cleaning process if necessary.
