A chemical treatment for diesel engines to reduce soot emissions and help clean and regenerate the particulate filter. Reduces soot formation during the fuel combustion cycle. Helps to reduce maintenance costs related to the manual regeneration of the blocked soot filter whilst optimising combustion and lowering fuel consumption. Especially suited for city driving. Can be used in combination with built-in regeneration systems. For diesel engines with all types of diesel particulate filter. For diesel and biodiesel up to B30. Only add to the fuel tank.
