How Long Does a DPF Last?

A diesel particulate filter (DPF) is a filtering device installed in diesel-powered vehicles that is meant to entrap the soot produced by diesel engines. This makes diesel engines slightly less harmful for the environment, especially since the grime can be quite pollutive. To drive on UK roads, having a DPF installed is a must – otherwise the Ministry of Transport (MOT) can inflict heavy fines.

Despite DPFs lasting a long while, they do have a limit to how much they can run for. For those that own a diesel-powered vehicle, it is essential to know how long their DPF will remain functional. Turborevs answers this question in detail, explaining how long your DPF lasts, along with ways to extend its lifespan.

How Long Does a DPF Last?

In general, a DPF filter should last for approximately 100,000 miles before a need for a replacement arises. However, this number can vary significantly based on how well-maintained the DPF is. A poorly maintained DPF may last a lot less than the specified number, while a regularly-maintained one may even reach 150,000 miles before needing a replacement.

Maintenance depends on how regularly regeneration takes place within the DPF, or the number of times you use a DPF cleaner. Moreover, the type of fuel that you use also plays a role in your filter’s health. Ensuring that the overall health of your DPF remains optimum is key to enable maximum longevity of your diesel particulate filter.

Ways to Extend a DPF’s Lifespan

Since the filter’s longevity entirely depends on how well you maintain it, the key here is to ensure regeneration takes place regularly. You can do this by taking your vehicle on the motorway to allow passive regeneration to take place, or pour a DPF cleaner into your filter to allow the soot to be brunt off at lower temperatures. 

Since a clogged-up filter can lead to a build-up of gases within the exhaust, not only will the DPF be affected but the engine will also take a hit. Therefore, ensuring that your diesel particulate filter is never jammed up is a must. Also, avoid using low-quality fuel as that can hinder the passive regeneration process.

Conclusion

Despite being a crucial part of diesel-powered vehicles, diesel particulate filters have a limited lifespan and must be replaced after a while. However, understanding how long one will last is essential to timely have it replaced. Moreover, understanding the different ways to increase your DPF’s longevity is also important so that your filter would last you much longer than its average lifespan.
