The best diesel service shop!

SWD is the best diesel service shop in the world! No kidding. I used to take my Ford Excursion to the dealership and, after getting completely ripped off for years, I found honest expertise at SWD. Talk to James or Danny or anyone there and expect solid, friendly service. Thanks SWD!

Horrible Service

We were coming into St George and knew we had blown a Fuel Injector but was not sure how many or how bad it was so I called and the guy on the phone was super nice and said he could get us in, when we arrived on site the guy that came out was very rude talking crap about the truck we were driving and how we were responsible for the truck breaking down and how he was the best at fixing what was wrong but that he could not help us until Monday, we let him know we were only in town for the weekend and need to leave by Sunday he said that was our problem , we asked him if he knew of any other shops in the area that could help us he said none as good as us, I guess you tuff out of luck huh, we asked him were the nearest dealership was and he said good luck with that we do there work for them when they are full , all in all I would never recommend this shop to anyone, I wanted to punch the guy in his face the way he was talking to us

They saved my run.

I was very satisfied with the service and quality of personell at Southwest Diesel. I was in my 06 Pete in a round about and my truck shut down completely and Southwest Diesel was able to set up everything from Tow to fully repaired. All I had to do was put out my safety cones and wait for help that came in less than twenty minutes.The nite repair tech on duty was honest and informative on my choices in my situation and helped me to find the laest expensive way to get me back on the road.I was back on the road in less than twenty hours from begining to end and now I will always send them my buisness for all my preventitive maintenance as well as repairs I can limp to them. They are worth going out of your way to use these guys.Alan FranklinFranklin Universal Transport
