Truck Series DPF Protector - Liqui Moly 20258

Product Information

Your vehicles diesel particulate filter, also known as DPF, is responsible for removing soot and particulates from the exhaust. On diesel vehicles the combustion process is "dirtier" than conventional gasoline powered engines. Due to environmental regulations all modern diesel engines are equipped with a DPF system. Some modern vehicles have the ability to clean out the filter using a process called active regeneration which essentially burns off the soot and debris that builds up inside the filter. In some cases, active regeneration cannot clean the filter adequately enough which can cause an array of performance issues. If this occurs you will get a CEL warning on your instrument cluster with codes associated to a failed or blocked DPF.

About Liqui Moly

All LIQUI MOLY products are created by close solidarity with the automotive, two-wheel and commercial vehicle industry. That's why Liqui Moly solutions are always on par with state-of-the-art technologies and sometimes even a good distance ahead. The recipes for LIQUI MOLY high-tech products are largely based on our own developments, that we continuously test and develop. The LIQUI MOLY full range, with more than 4,000 products, offers you lubricants, additives, car care products and chemical repair tools with integrated use guarantee.

LIQUI MOLY offers the matching motor oil for every vehicle in the world. Liqui Moly engine oils have a variety of approvals by German and overseas car manufacturers or fulfill the requirements of the producers. And, even here, there are still differences: A manufacturer approval means that the oil fulfills certain minimum requirements. But LIQUI MOLY goes beyond those requirements and develop oils that, for example, have a higher cleaning performance than what is required by the manufacturer.

Every mile driven costs a tiny bit of engine longevity. The reason: Friction and wear. A creeping process, that is often accelerated by poor fuel quality and deposits of old lubricants. However, regular maintenance of the oil and fuel circuit can usually restore engine performance to its original level. Without much effort, but with a great deal of effect. When it comes to gear oil a similar thing can be said.

The fact that LIQUI MOLY products shine, and, with a high level of innovation, deliver what they promise, is confirmed again and again by independent testing institutions, in which we regularly pass with flying colors. Approvals by the automotive industry and the fulfilling of the highest specifications are also a matter of course.
