Fuel additive to protect DPFs

Published:  06 November, 2017

LIQUI MOLY has developed a fuel additive for diesel particulate filter (DPF) protection.

DPFs keep damaging soot out of the exhaust gases. Regeneration kicks in at set intervals once the exhaust gas reaches a certain temperature. Thus, the soot particles combust in the filter and it remains permeable. However, vehicles used mainly for short distances or in urban traffic often don't reach this temperature. This means  soot isn't completely combusted and it clogs up the filter more and more. The engine performance drops until finally the powertrain gives up completely. At this point, the only thing that will help is the replacement of the filter. Instead of taking place at 100,000 kilometres, this can occur as early as 20,000 kilometres.

 The new additive from LIQUI MOLY is added before fuelling every 2,000 kilometres. The contents of a 250 ml can is enough for 50 to 70 litres of diesel fuel and is suitable for all vehicles with a diesel particulate filter, as long as they don't have an electronically controlled additive tank system for filter regeneration, as is the case in Citroen and Peugeot vehicles.
