DPF systems can be found on most modern diesels and they trap and hold any harmful emissions. The stored deposits are eventually burnt off at high temperatures and this is a process calledDPF regeneration. This process usually happens at speeds over 50 MPH but if you don’t achieve these speeds regularly, it can lead to the DPF becoming blocked. This is where a DPF cleaner becomes useful because it’s designed to clear the deposits blocking the filter.

After having troubles myself with a blocked DPF in the past, we have since always used DPF cleaners. Over the years, we have tested a number of formulas (such as the photo we took above). Therefore, along with our own experience and plenty of research, we are able to rate and recommend a number of DPF cleaners.

If you are looking for a quick answer, the best DPF cleaner is theForte DPF Formula, which is suitable for all diesel engines and aids passive regeneration of the DPF. However, if you are able to spray the cleaner directly into the diesel particulate filter, theK2 DPF Sprayis the best alternative.

Best DPF Cleaner Overview

  • Best Overall: Forte DPF
  • Best For Regular Use: Millers Oils Cleaner
  • Best All-Rounder: Wynn’s WY28272

  • Best Budget: STP Cleaner

It’s important to note that the formulas need to be used in accordance with their instructions for the best results. Some may require regular use every 3,000 miles in order to clear trapped soot that’s clogging up the filter.

If you have been using the cleaner and there is no difference, we advise that you connect your car to anOBD2 scannerto confirm that the filter is actually blocked.

How We Rated

As mentioned earlier in the article, we have experienced a blocked DPF filter in the past and it was an expensive repair. However, with the regular use of DPF cleaners, we haven’t had an issue since and highly recommend them to anyone with a modern diesel car that features a diesel particulate filter.

As well as testing a number of cleaners, we also based our recommendations upon a number of factors. These included how easy they are to use, duration between the treatments, additional qualities and value for the money.

Conclusion

DPF cleaners are suitable for most diesels orbiodiesel enginesand may require regular usage to keep the DPF clean. If you find that they aren’t as effective as you would expect, you should try and go on a “spirited” drive whilst keeping the RPM’s high. You could also drive on the motorway and keep the car in a lower gear whilst travelling at 60 to 70 MPH.

All of our recommendations are suitable for a range of budgets and available in bulk buy options for extra value for the money. To avoid disappointment, we advise that you purchase from a reputable brand for complete peace of mind.
