There have been many myths and misconceptions about aftertreatment systems. Some people think you can just ignore them until the dreaded “derate”. Others think you can base all emissions servicing on the OE specs alone. That’s just not the case in the real world.
OE service recommendations are between 200,000 – 300,000 miles, or 4500 hours – whichever comes first. Aftermarket manufacturers of DPFs recommend cleaning at 50,000 – 70,000 miles, or 1,000 hours – whichever comes first. These numbers are generally overly optimistic and presume perfect operating conditions.
Based on our experience, Filtertherm® recommends servicing your DPF at least once a year. Removing the soot regularly will help extend the life and performance of your fleet’s aftertreatment systems and engines. Hardened ash build-up in the system restricts the flow and often causes unnecessary engine issues or failures.
It’s vital to establish a maintenance schedule that also takes into consideration the real-world driving conditions of the vehicle. Trucks that are run in stop-and-go traffic or high idling situations often need dpf cleanings at closer intervals.
Proper DPF maintenance is key to a healthy truck & in turn a HEALTHY FLEET.
