Purpose-Built Diesel Truck Modifications in Oxnard, CA
Diesel Modifications Start With Knowing Your Engine
A modification is only as good as the engine underneath it. Before making changes, you need to know whether fuel delivery, boost, cooling, electronics, or the engine's internal condition could affect the result.
That’s where Max-Dieseltronics stands apart. We specialize in advanced diesel diagnostics and troubleshooting, combining electronic testing with extensive mechanical engine capabilities.
Our mobile diesel services include:
- Electrical and electronic engine diagnostics
- Injector and injector cup service
- High- and low-pressure fuel system diagnosis and repair
- Turbocharger diagnosis and repair
- Cylinder head removal and installation
- Internal and in-frame engine repairs
- Complete diesel engine overhauls
- Cooling system and water pump service
- Air compressor service
- Valve adjustments
- EGR component work
- Aftertreatment and emissions diagnostics
- Oil, fuel, coolant, and other leak diagnosis
Rather than assuming a modification will solve a performance complaint, we can troubleshoot the engine first. That helps separate an actual mechanical or electronic fault from a change you want to make to your truck.
Mobile Diesel Service Built Around Your Equipment
No conventional shop visit is required. Max-Dieseltronics operates as a mobile-only diesel service, bringing diagnostics, troubleshooting, engine repair, and maintenance capabilities to your location in the Oxnard area.
That mobile approach is particularly useful for commercial trucks and equipment that can be inconvenient or costly to transport.
Preventive maintenance matters even more when you’re putting more demands on a diesel. We can inspect key engine systems, track down leaks, address cooling or fuel-system concerns, and catch developing problems before they interfere with performance. The goal is to ensure the engine supporting your modifications is ready for the work you expect of it.

FAQs
Where Do You Provide Mobile Diesel Service?
We’re based in Oxnard, CA, but our services are available within approximately 50 miles. We bring diesel diagnostics, troubleshooting, engine repair, fuel system service, and preventive maintenance directly to your truck or equipment, eliminating the need to bring it to a conventional repair shop.
What Types Of Diesel Equipment Do You Work On?
We service Ford, Ram, and Chevy/GMC diesel pickups as well as medium- and heavy-duty trucks, construction and off-highway equipment, and commercial or industrial diesel machinery throughout the Oxnard, CA area.
Why Diagnose A Diesel Before Making Modifications?
Diagnostics establish the engine's current condition before you make changes. Fuel-pressure problems, injector faults, boost issues, sensor failures, cooling concerns, or internal engine problems can all affect performance. Identifying those issues first gives you a clearer picture of what the engine actually needs.
Can You Handle Major Engine Repairs?
Yes. Our diesel engine capabilities include fuel system repair, turbocharger work, cylinder head removal and installation, internal engine repairs, in-frame repairs, and complete overhauls. We also diagnose cooling, electrical/electronic, EGR, aftertreatment, emissions, and leak-related concerns.

Customer Testimonials
Can't say enough positive things: punctual, knowledgeable, hard-working, problem solver, positive attitude...it was a pleasure and we greatly appreciate having so many assets up and running!
I had an ECM on a caterpillar 3126 motor Motorhome which is very hard to get programed in California due to software costs and could not fine a mobil guy. I contacted Max who asked for some engine numbers and said would call back. the next day called back and came out Saturday morning pluged his system into my computer and within couple hours he fixed the issues. I found Max very smart and No BS. besides being a nice guy I trust him going forward and would recommend his services. i live in Ventura county
Great service and communication. We have used Max now for our Kubota Skidsteer and also our JLG Telehandler. He got us back up and running quick at our jobsite which was a major plus not having to load up and haul to a repair shop. Highly recommend their services!
