Keep Emission Systems Running Without Derates

Plan DPF Regen & After-Treatment Services in Midland

Your diesel engine's after-treatment system keeps emissions under control and your truck running legally, but soot buildup and sensor failures can trigger derates and shutdowns. In Midland, where stop-and-go oilfield traffic accelerates DPF clogging, Lonewolf Diesel provides DPF regen, cleaning, and diagnostics to keep your after-treatment system functioning correctly. Our technicians evaluate DEF systems, sensors, and exhaust flow to ensure compliance with manufacturer standards.


We support trucks across Freightliner, Kenworth, Peterbilt, Mack, International, and more, addressing repeated regen cycles, warning lights, and performance issues. Midland's dusty environment and heavy-duty operations put extra strain on DPF filters and after-treatment components, making regular service essential. Our team uses factory-grade diagnostic tools to measure backpressure, test NOx sensors, and verify DEF injection rates.


Schedule your DPF service in Midland at the first warning light to avoid costly shutdowns.

What's Included in This Service?

When you bring your truck in for DPF regen and after-treatment services in Midland, we start by scanning for fault codes and evaluating soot levels in the diesel particulate filter. Our technicians perform forced regens when necessary, but we also inspect the entire system to identify underlying issues that prevent passive regen from working correctly. This includes checking exhaust temperature sensors, verifying turbo function, and testing DEF injector operation.


Lonewolf Diesel provides DPF cleaning when filters are too clogged for regen to work effectively. We use professional-grade equipment to remove ash and soot buildup without damaging the filter substrate. Technicians evaluate DEF systems, sensors, and exhaust flow to ensure your truck meets emission standards and runs without derates.


After service, we test the system to confirm proper regen cycles, sensor readings, and exhaust flow. You'll leave with a truck that runs cleaner, performs better, and stays compliant with manufacturer requirements. Midland's oilfield traffic demands reliable after-treatment systems, and our services keep your truck on the road.

Why Locals Choose This Option

DPF and after-treatment systems are complex, and understanding what's involved in service helps you stay ahead of problems. Below are answers to common questions about our DPF regen and after-treatment services.

What causes a DPF to become clogged?
Soot buildup from stop-and-go driving, short trips, and low exhaust temperatures prevents passive regen from occurring. Midland's oilfield traffic conditions increase the risk of clogging.
How often should I have my DPF cleaned?
Most trucks benefit from professional DPF cleaning every 150,000 to 200,000 miles, but driving conditions and warning lights may require more frequent service.
Can you force a regen if my truck is in derate mode?
Yes, we perform forced regens using diagnostic tools that initiate the process manually. However, we also diagnose why the truck entered derate mode to prevent future issues.
What is DEF and why does it matter?
Diesel Exhaust Fluid (DEF) is injected into the exhaust stream to reduce NOx emissions. Low DEF levels, contaminated fluid, or injector failures can trigger warning lights and derates.
Do you service all truck brands?
Yes, we work on Freightliner, Kenworth, Peterbilt, Mack, International, and other major diesel truck brands. Our team is trained on the latest after-treatment systems and emission controls.

After-treatment systems keep your truck running legally and efficiently, and regular service prevents expensive downtime. Our team is ready to handle DPF regen, cleaning, and diagnostics with precision and care. Reach out today to schedule your DPF service in Midland.
