Today wasn’t just about tune-ups and tire rotations — it was about togetherness. We fired up the grill, cranked up the good vibes, and shared some serious laughs (and burgers and dogs) right here at Craig’s Car Care. 🍔🌭🔥

Avoid Costly Downtime: Diagnosing and Preventing DPF Failures in Heavy‑Duty Trucks Learn how to keep diesel particulate filters healthy, reduce unexpected repairs, and maximize uptime for your fleet in Carol Stream, IL. Why DPF Health Matters The diesel particulate filter (DPF) traps soot before it exits the exhaust. When it plugs, your truck can derate or shut down, leading to: Unplanned roadside calls and towing fees Costly filter replacements or bake‑outs Missed delivery windows and frustrated customers Higher fuel consumption due to backpressure A proactive DPF strategy protects both your bottom line and your reputation. What Causes DPF Problems? Short haul or excessive idling – not enough heat for passive regen. Poor quality fuel or excessive oil consumption – accelerates soot load. Failed sensors (ΔP, EGT) or DEF system issues – block active regens. Ignoring early warning codes – small issues snowball into full plugs. Step 1: Watch for Early Warning Signs Rising differential pressure readings More frequent parked‑regen requests Drop in fuel economy MIL or “Check Aftertreatment” lights Logging these trends lets you intervene before a forced derate. Step 2: Confirm with Diagnostics Use OEM software or a trusted scan tool to: Pull active and inactive aftertreatment codes Compare ΔP, DOC inlet, and outlet temps at idle and high idle Check regen history and ash/soot load estimates Document findings to build a maintenance timeline for each VIN. Step 3: Perform Proper Regeneration Passive Regen – Highway runs at operating temp burn off soot naturally. Active Regen – ECM injects fuel to raise exhaust temps when passive isn’t enough. Parked Regen – Manual command when dash prompts or after repairs. Ensure: Engine oil is at correct level (over‑fills can raise soot) No exhaust leaks upstream of the DOC DEF quality is within spec (32.5 ± 0.7 %) Step 4: Schedule Cleaning Before It Plugs Mileage / Hours Recommended Action 200–250 k mi (or 4,000 engine hrs) Remove DPF & DOC for professional bake & blow 400–500 k mi Ultrasonic wash or replacement depending on ash load Adjust intervals based on duty cycle and soot trends. Step 5: Optimize Fuel & DEF Quality Source ULSD from reputable suppliers; check for water or microbial growth. Use OEM‑approved oil to minimize ash. Store DEF in sealed, temperature‑controlled containers; discard if contaminated. Step 6: Leverage Telematics Data Modern telematics platforms (Geotab, Samsara, etc.) stream ΔP, EGT, and regen counts in real time. Set alerts for: ΔP > 3 psi at cruise 2 active regens per 100 mi These flags trigger preventive service before the truck reaches the shop on a hook. Step 7: Train Drivers & Technicians Drivers Respond promptly to parked‑regen requests Avoid unnecessary idling and lugging Report warning lights immediately Technicians Validate sensor health at each PM Log regen statistics and ash estimates Inspect for exhaust leaks and injector issues that can poison the DOC The Bottom Line A disciplined approach—early detection, data‑driven service intervals, and driver education—can cut DPF‑related downtime by up to 60 %. Stay ahead of soot, and your trucks will stay on the road earning revenue.
