How to choose a DPF expert
Diesel particulate filters (DPF) require routine cleaning to remove ash that builds up overtime. Overall filter life decreases when impacted ash is left in the filter cells. The deeper the impacted ash becomes the harder it is to remove in subsequent cleanings. The risk of sintering increases when ash is left in the filter. Ash stuck in the filter causes cold cells and leads to premature soot plugging. The cleaner the filter is kept the longer the overall life. Most vehicles using a DPF system will have an on-board filter service monitor to indicate the filter condition and guide your DPF cleaning schedule. Western Peterbilt 
has repeatedly cleaned the same filters pulled annually on a preventative maintenance basis and returned them to the Green Tag range. Make a service appointment with Western Peterbilt (Tacoma or Anchorage) to keep your DPF clean and operating at peak performance. Call (800) 255-7383 and ask for the DPF service facility nearest you.
