What our customers say

Honest, Fair, Friendly

Best Diesel service in the South. Hands down. Great staff, honest, fair; and the friendliest folks you will encounter in a stressful situation.

Worked with my Business

Southeast Diesel has been worked on all my trucks for years. They are thorough and when they send your vehicle back out to you, you can rest assured it was repaired properly. They’ve done fuel injectors on two of my trucks. Their prices are fair and consistent with industry standards. They are also a Banks Power dealer which is great.

They’ve helped me out a lot! I’m a small business owner and they always do their very best to get me in and out so that I can keep operating. Last week I wasn’t going to be able to work because my factory brake actuator went south and I couldn’t haul. Since the new actuator wasn’t coming in for days, Mike Holtzhower loaned me the brake actuator out of his personal truck! They really take care of you here. Won’t be taking my vehicles anywhere else.

Truck Repair

Remarkable! Of course the first day of vacation headed out of town with a trailer attached when I started having issues. I showed up 10:00 on a Friday morning, full of doubt that they would even be able to look at my truck. They had me back on the road in a few hours. Honest shop, Honest staff all very helpful.

In the end- I think I got lucky that I found a great place to service my diesel on accident. This will be my go to shop for all things diesel. fair prices and great service. They happen to be a Banks Power and Amsoil dealer as well- right up my ally!

If your looking for a fair and honest shop this is the place!
