Who We Are
I started OnSite Diesel Solutions, LLC after years of keeping equipment running for my family’s construction business. From excavators to Freightliner trucks, I’ve been the one handling repairs, diagnosing issues, and figuring things out on the fly—right there in the field.
I didn’t learn this work in a shop. I learned it where the pressure’s real—on active job sites, where broken machines cost time and money. That’s what shaped the way I work: no shortcuts, no guessing, just solid repairs and straight-up answers.
Now I bring that same approach to other operators and owners across Loma Rica and the surrounding areas. Whether it’s a tractor, a trailer, or something in between, I’ll meet you where the machine sits—and get it fixed right.
This business wasn’t built to scale—it was built to serve. I keep it simple so I can stay focused: one truck, one set of tools, and one job at a time done the right way. If I say I’m showing up, I will. And when I do, I come ready to work.
I don’t overcomplicate what I do. I show up, I listen, and I solve the problem. That’s what matters to me—and it’s how I’ve earned the trust of folks who’d rather be working than waiting on a fix.

I didn’t learn this work in a shop. I learned it where the pressure’s real—on active job sites, where broken machines cost time and money. That’s what shaped the way I work: no shortcuts, no guessing, just solid repairs and straight-up answers.
Now I bring that same approach to the people who keep this area running — landowners, ranchers, and local operators across Loma Rica and beyond. I don’t ask you to haul it somewhere or wait around. I meet you where the machine sits, figure out what’s wrong, and get it fixed right.
I keep it simple so I can stay focused: one rig, one set of tools, and one person who needs it fixed now. I don’t show up to impress — I show up to help. When something breaks, it’s not about the machine — it’s about the work that’s stuck until it’s running again. I do my best to solve the problem, and I don’t leave until I’ve given it everything I’ve got.
No Travel Fees. No Overtime Charges. No Weekend Markups.
Tired of being hit with surprise fees just because your equipment breaks down off-hours or a mechanic has to drive a bit farther? We keep it simple and fair: one flat hourly rate, at your location within our service area. No extra charges for travel, no inflated weekend or overtime rates-just honest, transparent pricing and expert mobile diesel service when you need it.
Diagnostic & First Hour Fee
Our service begins with a comprehensive dealer-level diagnostic scan and a detailed report for your equipment or vehicle.
Flat-Rate Services
We offer transparent, flat-rate pricing for common maintenance and repairs, including:
-
Oil Change
-
Brake Service
-
Inspections
Self-Help Option
Once diagnostics are complete, we provide a clear report with part numbers and step-by-step recommendations. Want to do the repairs yourself? No problem-we’ll give you the exact information you need to fix it right the first time, saving you from unnecessary “parts swapping” and wasted expenses.
Why Choose Our Diagnostic Approach?
Many shops and mechanics guess at the problem, leading to repeated, costly part replacements (“parts swapping”). Our dealer-level diagnostics pinpoint the real issue, so you only repair what’s actually needed-saving you time and money.
