If you are not getting the oil changed in your diesel truck by these guys, you should. Price is reasonable and they know diesels. If you ve got questions or need more than an oil change, this is the place they know diesels. Need your diesel fixed or looking for more performance? This is the place.

Had an awesome experience with these guys. Trustworthy and extremely knowledgeable. You don't know how lucky we are to have this quality of diesel mechanic down near us. Before I found these guys I had to drive up on the Northside and beg to get in with a fleet mechanic, and if I was lucky maybe they would get my truck back to me in 3 weeks for a 2 day job. Having these guys around will get you every last mile possible out of your truck.

Awesome shop! I won't trust anyone else with my truck. Small privately owned shop, with a bunch of good honest guys

I would warn anyone taking their vehicle to this business to first read this review and to think twice.We dropped our diesel truck off to be diagnosed by these guys on a Wednesday. We stopped in at the garage on Friday morning and found the truck parked out by the road (as many are). My husband jumped out and to our surprise, the truck was left UNLOCKED. He locked the vehicle and carried on with his business, I believe addressing that with the employee via telephone later on. Monday rolled around and we finally got a diagnosis- turbos needed to be replaced. Cost? 6k. My husband stopped in to discuss further and again, found the truck UNLOCKED!!!As we discussed this overnight, we woke up Tuesday morning to find several fraudulent checks cashed out of our business checking account. My husband realized that he had left a checkbook in the center console of the truck and since our truck was parked by the road and left unlocked several times, it was easy for some jerk to open the door, look around and take whatever they wanted. Obviously, it was our fault that the checkbook was left, but there was ZERO apology. We clearly decided to go elsewhere for the fix, but the owner still made my husband pay the diagnostic fee of $160+, even though we were out thousands bc of his ignorance and irresponsibility.Not the end though .We took it to another reputable company and guess what?! THE TURBOS ARE FINE!!!! No need to spend SIX THOUSAND DOLLARS because THEY RE NOT EVEN BAD!!!WOW!!! Save your money and time and go somewhere honest and helpful!

They did an awesome job on the engine swap in my 2007 ford f550, not only was it done ahead of the initial estimated time frame, the price was better than the other local shops! Great set of guys with a wealth of knowledge over there!

So I was traveling through with my truck and camper when the truck started acting up. They squeezed us in and got us back on the road the next day. Can t beat that. Such good service I m bringing my other diesel 500 miles to have Andrew work on it. No one is more skeptical than me .TAKE IT TO THEM YOU WONT REGRET IT!!!Services: Auto windshield repair, General repairs & maintenance, Electrical, Engine repair, Oil changeServices: Auto windshield repair, General repairs & maintenance, Electrical, Engine repair, Oil change

Matt and his team at Underground Diesel went above and beyond to bring my truck back to life. Pricing was very fair and I couldn t be happier with the final product. Look forward to doing business with these guys in the future.
