About Diesel Specialists, LTD.

A Legacy of Service

Since 1983, DSL has grown alongside Houston’s industrial, energy, and transportation sectors. Our technicians and service staff take pride in the work they do—bringing technical skill, hands-on experience, and safety awareness to every job.

From preventive maintenance to complete diesel engine overhauls, we help companies avoid downtime and extend the life of their equipment. Many of our customers have trusted DSL for decades because they know our approach - honest communication, proven processes, and dependable results.

The Spirit Behind the Work

Every great company is shaped by the people who care deeply about what they do. At DSL, that drive runs through generations of diesel expertise—fueled by the same passion for engines, tools, and craftsmanship that first sparked this industry in Houston.

It’s a mindset shared by our leadership and our crew alike: a respect for the trade, a dedication to learning, and a belief that hard work and integrity never go out of style.

That spirit is carried forward every day by professionals like Leo, our General Manager, whose lifelong experience in diesel repair reflects the same values DSL was built on - commitment, quality, and passing knowledge on to others.
