What Our Customers Say

Rex Pierce

You have to take your vehicle here! Justin and the guys at Lone Star Diesel are amazing. I had an engine replaced, and not only was it done faster than I thought, but it also runs like a new one. They are courteous, knowledgeable, professional, and are customer focused. I was informed every step of the way, which was a change for me.

Susan Brown

These guys are really awesome. My friend brought her car in for an oil change, service was so good and personable, I later brought mine in. Clean, fast, friendly, good price. But it’s not like a quick lube… you can tell by the other things going on there-

Dax Patton

Had never been to the shop before, but passed by a lot as they’re close to my home. When I had an emergency with my FJ Cruiser, I called them up and they told me to come on down. They were very professional and attentive and had my vehicle repaired and ready by the end of the very next day.

Casey Hubble

I am enjoying the upgrades Justin and his team did on my truck. I appreciated the extra time they spent explaining the components that were to be installed and they were easy to work with on all ends. I also discovered cold brew coffee (which they have on tap) during my visit & it is delicious.

Robert Garza

I stopped in to ask about a check engine light on my 99 Mercedes SLK and possibly making an appointment. They said they could do it same day and get it fixed for me. These guys are great! I will be bringing my Mercedes here for any future service work.
