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.
Benefits of a clean DPF include:
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.
How can I tell if my DPF is causing performance issues?
Look for signs like frequent regens, decreased power, high fuel consumption, or white/blue smoke. These often point to DPF clogs, EGR malfunctions, or SCR issues. Regular diagnostics and DOT inspections can catch problems early.

Critical: ValueMy APU needed a simple oil change. I provided all filters. Job only takes a half hour at most, but they did the job in 28 minuets. Unfortunately, they charge a minimum of three hours labor, well over 300 bucks. Speedco or any loves will do it for just over a hundred dollars. So, if your truck's APU needs an oil change, take it to any loves or Speedco and save yourself a full day's wages.My APU needed a simple oil change. I provided all filters.

A "hidden" gem! I thought Angels Truck Service was for 18-wheelers but called and spoke with the owner, Paul, who was extremely nice and helpful. I went by the shop yesterday to see about getting tires mounted for John Deere lawn tractor. I was amazed at the exceptional customer service, the helpful attitudes, and the consideration of everyone one I encountered. I can't say enough nice things about Paul, Angels Truck Service and his guys! I highly recommend this business!!!A "hidden" gem!

PERFECT PLACE TO GET SCAMMED. Nearly $500 for a leaky radiator hose, charged for 10 gallons of antifreeze when the truck was almost full of brand new antifreeze which I guess nobody bothered to save, 2 hours of labor when they changed the hose in 10 minutes and a serious attitude problem when we asked about the shady bill. The hose itself costs $35.00 at the local dealer....In the end we just wanted to pay our bill and be on our way but they refused to accept our credit card and insisted on cash payment, fearing a claim because of their shady services. Lost nearly 5 hours and had to get the local police involved so that they would accept a DEBIT card because our driver did not have enough cash on him. STAY AWAY.PERFECT PLACE TO GET SCAMMED.
