What is DPF?
DPF (diesel particulate filter) treats your truck's exhaust by trapping particulate matter which is basically soot and ash. Diesel particulate filters have been a crucial part of a truck's emissions system. DPF's capture approximately 90% of diesel particles and soot preventing them from being released through the exhaust system.

DPF particulate filter

Benefits of a clean DPF include:

  • Improved vehicle performance
  • Increased fuel economy
  • Experience fewer regenerations
  • Lover maintenance costs
  • Extended DPF life

Cleaning

The DPF must be cleaned every 150,000 to 300,000 miles to remove the built up ash. The filter should also be cleaned if a fuel injector or turbo problem causes contamination with engine oil or non-combusted diesel. This contamination cause unwanted back pressure. Cleaning methods include air blasting, de-ionized water and a vacuum-like system. This must be done very carefully to avoid any damage to the filter. The particulate matter that is removed must be handled with extreme caution to ensure there is no exposure to the very fine contaminants.

DPF and Preventative Maintenance

The DPF is yet another component that must be tracked and maintained on a heavy duty truck. Ensuring regular preventative maintenance is performed on the DPF will do wonders in ensuring the long life of the DPF. Replacing air filters and fuel filters regularly along with using the correct type of oil for the engine will help prevent any unnecessary wear and potential damage with the DPF.

Critical: Professionalism, QualityI wouldn’t use the clowns again! Came in because my regen light was on and wouldn’t go off and check engine fault code was on. They preformed 2 parked regens and used their computer. They said I needed an ECU update, but I just had the ECU replaced 3 months ago. Then they tell me their computer can’t update the ECU because their software is out of date. But yet they still charged me $193.49 for using the computer. It was a complete waste of my time and money. They didn’t get anything resolved, they must be desperate for money!Service: Auto engine diagnosticI wouldn’t use the clowns again!

Paul was great with me, was broken down with leaking air line, got me out in a timely manner. Employees seem highly no l knowledgeable. Prices were given before with started (after they assessed problem). Everyone was super nice and friendly. I used to own a auto repair shop so I understand some of these reviews, one time we had a customer for an oil change, in our shop the car didn't start, he called police we assessed problem and his fuel pump went. One customer accused us of stealing her speakers! From what i saw this place is five star.Paul was great with me, was broken down with leaking air line, got me out in a timely manner.

Positive: Professionalism, Punctuality, Quality, ValueI will recommend anyone and everyone to Angel’s Truck Service. My family and I were on a road trip and were in desperate need of help with our lights. We walked into the shop and everyone was extremely busy there. Even with them being busy, Tyler came out to help us right away! He was professional and knew how to get the job done. Within 30 minutes my family and I were back on the road. We called 5 other RV/truck repair shops that all said they were too busy to help us. We are so thankful and grateful that Angel’s Truck Service understood that we had an emergency and jumped to the rescue. Thank you for helping make our trip safer and a much better experience.Service: ElectricalI will recommend anyone and everyone to Angel’s Truck Service.
