As fleets prepare for EPA 2027, DPF maintenance deserves a closer look.
In our last post, we compared how engine manufacturers are adapting their emissions systems. This time, we’re looking at the service intervals behind them.
OEM-published intervals depend on the engine generation and operating conditions. Some include hour or calendar limits. Others describe a mileage range tied to fuel consumption.
We’ve gathered selected guidance from Cummins, Detroit, Volvo, and International into a quick reference for fleet and maintenance teams. The comparison includes different engine generations, with the applicable conditions identified.
Before adding an interval to your maintenance plan, confirm the schedule and service procedure for your specific engine.
Save this reference for your next maintenance-planning discussion, or share it with the person who manages your fleet’s service schedule.
