The diesel particulate filter (DPF) in a diesel vehicle acts to keep grime and particulates out of the engine and exhaust system. But after time, this crucial bit of kit starts to get clogged up with soot and ash. A dirty DPF means lower engine performance and higher fuel costs.  And if you don’t deal with it, a dirty DPF will fail, damaging your engine and costing you thousands in repair costs.


Regular professional DPF cleaning from a reputable team like Applied Radiators will keep your filters free of dirt and keep your vehicle on the road. Keep reading to find out how.


Save on Fuel Costs

A clean DPF improves fuel efficiency. When the filter is clogged, the engine must work harder to push exhaust gases through. This leads to increased fuel consumption. By maintaining a clean DPF, your engine can run more efficiently, and you can save on fuel costs.


Lower Maintenance Costs

Clogged DPFs can lead to increased engine wear and cause damage to other components. Regular cleaning helps avoid these issues. You’ll save on overall maintenance costs.


Longer Engine Life

A clean DPF improves engine performance and longevity. Soot build-up can cause excessive engine strain, leading to premature wear and tear. Regular cleaning extends the life of your engine by maintaining its efficiency and preventing damage.


Better Performance

A clean DPF means better engine performance. You’ll notice enhanced acceleration and the engine will function smoother. The end result is a more reliable and enjoyable driving experience.
