Diesel particulate filter protector from LIQUI MOLY.
The service life of diesel particulate filters is limited and can fall significantly below the manufacturer guidelines. One of the main causes of this is soot, the filter’s arch enemy. However, a development by LIQUI MOLY is here to help, according to the company.
The Diesel Particulate Filter Protector is a fuel additive that keeps the filter clean and allows it to last longer. The additive should be added before fuelling every 1,250 miles. The contents of a 250ml can are enough for 50 to 70L of diesel fuel.
