More and more diesel vehicles have a particulate filter. Their service lives are limited and can fall significantly below the manufacturer guidelines. One of the main causes of this is soot. However, a new development by LIQUI MOLY is here to help: the Diesel Particulate Filter Protector. The fuel additive keeps the filter clean and allows it to last longer. It also expands the service spectrum of garages.
Diesel emissions harm the environment and are harmful to people’s health. That’s why exhaust gas treatment is becoming increasingly important. Particulate filters 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, this is dependent on driving habits: vehicles used mainly for short distances or in urban traffic often don’t reach this temperature. Meaning the soot isn’t completely combusted and it clogs up the filter more and more. The engine performance drops until finally the power train gives up completely. At this point, the only thing that will help is the costly replacement of the filter. Instead of at way over 65,000 miles, this can occur as early as 10,000 miles. In order to avoid this scenario, additive specialist LIQUI MOLY has developed a fuel additive for prophylaxis: Diesel Particulate Filter Protector. “If this is regularly used, soot is unable to bother the filter. This avoids expensive repairs and downtimes,” says Reiner Schönfelder, application engineer at LIQUI MOLY.
The additive is added before fuelling every 1,250 miles. The contents of a 250 ml can is enough for 50 to 70 liters 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.
