Highly effective additive that reduces the build-up of particulates and thus increases the service life of the diesel particle filter Suitable for diesel vehicles with diesel particle filters, provided these have not already been equipped with an electronically controlled additive tank system for filter regeneration (as used by Citroen and Peugeot, for example) Add the diesel particle filter protector to the fuel immediately before filling up after every 2,000 km The container is sufficient for 50 -70 litres of diesel fuel Note: Avoid excess dosage and use in combination with diesel soot guard! Ensures optimum combustion of the fuel, reduces soot formation, lowers emissions and extends the service life of diesel particulate filters Vehicles used for short trips and city traffic are especially affected by clogged diesel particulate filters
