Our Story
18 Years Keeping Orange County's Fleets Running
OC Clean Truck is a division of Premier Automotive Repair LLC, a diesel fleet repair business that has been serving Orange County since 2008. Over nearly two decades, we've built lasting relationships with some of the biggest companies in their industries — fleets that can't afford downtime and won't settle for anything less than expert service.
When CARB launched the Clean Truck Check program, we were among the very first companies in California to become credentialed and begin testing. We didn't follow the industry — we helped shape it. That early commitment gave us a head start that still shows today in our processes, our equipment, and our expertise.
We built OC Clean Link to take that expertise even further — combining our deep diesel knowledge with remote telematics technology so fleets can get tested and stay compliant without pulling trucks off the road.

Who we serve
Trusted by large fleets — including California's utility companies.
Our client list includes some of the largest and most compliance-sensitive fleet operators in California. We test for major corporations, large commercial fleets, and California utility companies — organizations that operate under strict regulatory scrutiny and can't afford compliance gaps.
- Major California utility companies
- Large commercial and industrial fleet operators
- Multi-truck corporate fleets across multiple industries
- Companies with strict internal compliance requirements
Large fleets. High stakes. Zero room for error.
If your fleet is large enough that compliance has to be right every time, you're exactly who we built this service for.
One of the First in California
When the CARB Clean Truck Check program launched, most shops were still figuring out what it meant. We were already credentialed, staffed, and testing. Being a pioneer in this space means our team has more real-world experience with Clean Truck Check compliance than almost anyone in the state — and that experience directly benefits every fleet we serve.
