Diesel Particulate Filter Cleaning and Maintenance | Capitol Chevrolet

October 15th, 2025

Modern diesel work trucks are built with a diesel particulate filter (DPF), an emissions-control device designed to capture and store soot and other harmful exhaust particles before they're released into the air. Over time, however, the filter fills up with particulate matter and must be cleaned or serviced to maintain performance. A DPF that isn't maintained can cause increased back pressure in the engine, reduced fuel efficiency, and even trigger warning lights that sideline your truck until repairs are made. DPF cleaning is a specialized maintenance service that restores the filter's capacity. At Capitol Chevrolet in Salem, OR, our technicians use professional-grade equipment to safely remove soot and ash from the filter without damaging its structure. We also perform a thorough inspection of the system to confirm it's operating as it should. For trucks that see heavy-duty cycles-such as hauling, construction, or long-distance transport-keeping the DPF in good condition isn't just about efficiency, it's about staying compliant with emissions standards. Regular DPF service means your truck remains powerful, fuel-efficient, and road-legal, helping you avoid costly downtime and unexpected fines while ensuring your business stays on track.

Why Skipping DPF Care Can Cost You

The DPF isn't just another part-it's critical for both performance and compliance. When a DPF becomes clogged, exhaust gases can't flow freely, forcing the engine to work harder and burn more fuel. This often results in sluggish acceleration, reduced towing power, and higher operating costs. Worse yet, ignoring a clogged filter can lead to forced derates, breakdowns, or expensive replacement of the entire unit. Regular DPF cleaning ensures soot is cleared out before it becomes a problem, keeping your truck efficient, powerful, and ready to handle heavy workloads without unexpected setbacks.

When's the Right Time for DPF Service?

The ideal DPF cleaning interval depends on how your truck is used. Light-duty trucks that drive longer distances may need service every 100,000 miles or so, while heavy-duty work trucks that operate in stop-and-go traffic, construction sites, or short routes may require cleaning as often as every 50,000 miles. Warning lights on your dashboard are also a clear signal that it's time for attention. Capitol Chevrolet's service team can help you build a schedule based on your workload, ensuring your truck's emissions system stays healthy and compliant while avoiding costly downtime.
