If you own a diesel anywhere near Berea, KY, save yourself the trouble and call Preston Jones at PJ Diesel. I brought him my 2021 Silverado Duramax (L5P) and the whole experience was as good as it gets. Preston is honest and upfront with you from the first conversation. He got back to me fast every time I reached out, and the turnaround on my truck was quick. He knows these trucks inside and out, and his pricing is fair. He came in less expensive than a lot of other shops, and the work is excellent. What really sets him apart is how he treats his customers after the job is done. Any time I've wanted to pick his brain about my truck since then, he's been glad to share what he knows. My truck is running better than it ever has. I'm in Richmond, and I would've driven a lot farther than that for work this good. A reliable diesel mechanic you can trust is hard to find, and I couldn't ask for anything better. I'd recommend PJ Diesel to anyone in Madison County or beyond.

Serving Lexington
Lexington is the second-largest city in Kentucky and the center of the Bluegrass region. Interstate 75 and Interstate 64 meet on the north side of the city, and New Circle Road loops around its core, so there is constant truck traffic moving freight, horses and equipment. The surrounding horse farms and agricultural land keep a lot of heavy-duty pickups on the road, many pulling horse trailers and flatbeds. City driving, interstate hauling and long rural stretches all show up in a typical Lexington diesel's history. Winter brings cold starts and salted roads, and summer heat works cooling systems hard in traffic on the interstates.

Why Lexington customers need this work
Diesel trucks in and around Lexington often pull horse trailers, livestock trailers and equipment, which means long stretches under load. That puts stress on turbos, injectors, transmissions and cooling systems. Heavy city traffic adds idle time and short trips that can clog emissions parts. When a diesel starts losing power, smoking or throwing codes, a shop that focuses on diesel can sort out whether the cause is fuel, air, emissions or something deeper in the engine. Regular maintenance on fuel filters, oil and coolant also goes a long way for trucks that work hard.
