At Diesel Doctor, we specialize in the diagnostics, repair, and maintenance that general shops overlook — Cummins, Detroit Diesel, Power Stroke, and everything in between.
Whether it's scheduled maintenance or a breakdown you can't afford to ignore, we've got the expertise and equipment to get you back on the road.
Advanced scan-tool diagnostics for all major diesel platforms. We read the codes, trace the root cause, and fix it right the first time.
From rebuilds to complete replacements — Cummins, Detroit Diesel, International, and more. We handle the work that keeps your rig going for the long haul.
Scheduled oil changes, filter replacements, fluid services, and inspections designed to catch problems before they strand you.
Transmission rebuilds, clutch replacements, and driveline repairs for heavy-duty trucks and commercial equipment.
Injector testing, fuel pump repair, and complete fuel system diagnostics. We keep your injection system running clean and efficient.
Complete brake inspections, repairs, and air system service for commercial and heavy-duty vehicles. Safety-first, every time.
Diesel Doctor was founded on a simple premise: diesel engines are different, and they deserve mechanics who understand them inside and out. While general repair shops cover a little of everything, we live in the details — the fuel injection timing, the turbo boost curves, the ECM calibrations that separate a running engine from a reliable one.
Located on Highway 98 W in Foxworth, we serve commercial fleets, independent owners, and local businesses across south Mississippi. No job is too big or too involved. If it runs on diesel, we know how to make it run right.
We don't swap parts and hope for the best. Every repair starts with a proper diagnosis and ends with a job done right.
We don't spread ourselves thin across every vehicle type. Diesel is our focus, and that focus shows in the quality of our work.
We'll tell you what your vehicle actually needs — not what you might be expecting to hear. No upsells, no unnecessary repairs.
We use OEM and premium aftermarket parts. Your truck deserves components that can handle the torque, the heat, and the miles ahead.
Time is money when you're running a business. We prioritize efficient repair cycles so you're back on the road sooner.
Whether it's a scheduled service or an urgent repair, Diesel Doctor is here for you in Foxworth and the surrounding communities. Give us a call or stop by — we'd rather talk to you before the problem gets worse.
