Oilfield Equipment Repair in San Antonio, TX & South Texas
Call Today for Mobile Diesel Repair
South Texas oilfield work doesn’t stop — and neither can your equipment. From rig moves and pad builds to pipeline and hauling operations, every machine is critical. When diesel equipment breaks down, production slows, deadlines slip, and profits drop. That’s why Lone Star Diesel Solutions provides mobile oilfield equipment repair in San Antonio, TX and across the Eagle Ford Shale region.
Whether you’re running pump trucks near Pleasanton, moving rigs along I-37 toward Corpus Christi, or hauling pipe through Karnes City, our mechanics bring diesel expertise directly to your site — no matter how remote.
Mobile Diesel Repair for Oilfield Operations
Oilfield projects rely on heavy-duty diesel equipment that runs long hours under extreme conditions. Our mobile repair units are equipped to handle breakdowns where they happen — in fields, on access roads, or at drilling sites.
We repair and service:
Oilfield service trucks (water trucks, vacuum trucks, winch trucks)
Frac pumps & pressure pumping equipment
Generators & light towers
Rig and pump engines (Caterpillar, Cummins, Detroit, MTU, etc.)
Dozers, loaders & excavators used in site prep
Pipeline support equipment
Diesel-powered compressors & pumps
If it’s diesel-powered and critical to your operation, we keep it running.
Roadside & Remote Site Coverage
Oilfield breakdowns rarely happen near a city — they happen in the middle of nowhere. That’s why LSDS covers a wide service area across South Texas oilfield country:
Eagle Ford Shale (Karnes, La Salle, McMullen, Live Oak Counties)
I-37 corridor between San Antonio and Corpus Christi
Highway 97 through Pleasanton, Jourdanton & Cotulla

The Cost of Downtime in the Oilfield
Oilfield operations run on unforgiving schedules, and downtime isn’t measured in hours — it’s measured in lost revenue. A downed frac pump, stalled service truck, or idle rig engine can cost operators anywhere from $10,000 per hour to over $300,000 per day, depending on the scale of the project. For hauling and support fleets, breakdowns can also lead to missed contracts, delayed drilling schedules, and regulatory penalties.
Our mobile diesel service reduces downtime by as much as 70%, helping crews stay productive and keeping your operation profitable.
