When to Clean your Diesel Particulate Filter

Enviro-Exhaust-logoA Diesel Particulate Filter (DPF) is designed to remove particles from your exhaust emissions to make it compliant with environmental standards.

The problem is that these "particles" are trapped in the filter and regeneration alone does not remove them all!

Diesel particulate filters should be cleaned as regularly as you service your truck!

If you are experiencing any of the following issues, there is a good chance that your DPF needs cleaning:

  • Frequent regeneration
  • Losing engine power
  • Fuel consumption increasing
  • Exhaust back-pressure increasing

Failure of fuel injectors or turbochargers resulting in contamination of the filter with raw diesel or engine oil can also necessitate cleaning.
