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. Tested for compatibility with turbochargers. Fully compatible with all conventional diesel and biodiesel fuels. Contents sufficient to treat up to 75 liters of fuel. Eliminates diesel knocking, increases operational reliability, boosts the cetane number, guarantees optimum combustion, provides good corrosion protection, is highly economical, reduces deposits, and cleans the fuel system. For preventive use, add to diesel fuel according to inspection intervals. For remedial use, disconnect fuel feed and return lines, insert into the diesel purge, start the engine, run at various speeds, and switch off before the container is empty. Reconnect fuel lines and check for leaks. Repeat if necessary.
