The fact that this shop isn’t gouging like most others is impressive. I’ve been stolen from a few times before coming to Mr Diesel, With shabby results from the places I’ve been. Thanks to Mr Diesel my 96 12 valve is running better than it ever has as long as Ive owned it. A 660,000 mile truck too mind you. And also because this crew of gentlemen understand the nature of the beast for a welding rig, they got it in and out super fast with purpose. Thank you Mr Diesel, I appreciate you. - 5 star review on Google

We want to thank you for the service you provided us when we broke down just outside of Cheyenne this past Tuesday. We were pulling a 5th wheel with a Ford F-250 super duty. You got us in right away and had us fixed and ready to continue the next day. Thank you so much for helping out of town strangers so quick and professionally. We’re on our way today and will always remember Cheyenne as one city that is full of good and helpful people. Thank you Reg and Sandra McKerlie Pensacola Florida

I have a 2002 Dodge Cummins and George and his staff diagnosed my old diesel with a leak from the rear main. I paid Mr. Diesel for the repair and to my dismay I still had a leak. George brought my truck back in and said it was the valve cover gasket and was misdiagnosed. He said the valve cover gasket was going to be repaired free of charge as it was misdiagnosed. This might sound bad however, my truck to this date doesn't leak a drop of oil and has 130k on it. Good crew and very professional!

I have a 2006 Jeep Wrangler Rubicon TJ and brought it to George for a transmission replacement. The TJ manual transmission 6 speed is plagued with problems and George didn't know this. His go to transmission builder is Jasper. It took three builds (in and out), which George had to put in and take out to get a tranny, which shifted like factory. I don't blame this on Jasper or Mr. Diesel at all, this is just a horribly problematic transmission Jeep put in TJ's. However George and his crew never waivered and stood by me as the customer and worked with Jasper and made everything right. George and his wrench crew is the most professional bunch of individuals I have run across in a long time. This wrench crew sets the standard for the rest of vehicle repair community. I will always recommend this bunch to repair any of my family or friends vehicle's.

A great local business that cares about the work they do.  I would recommend to all my friends. - Casey H. (5 star review on Yelp)

George and his crew are amazing. Hands down the best diesel shop around. I had many issues with my 6.0 and they fixed everything fast and for a fair price. Great customer service. In the past I have found other shop's are condescending and talk down to me because I am a female but, not here. Just a wonderful shop! Thanks for all your hard work guy's!

I brought my 2001 Dodge Ram 2500 truck into the shop. It gelled up on me. The staff was super friendly and informative and they got me in and out right away. I just want them to know I greatly appreciate it. Thanks Guys

Outstanding service! I am a transporter from several states away. I was broke down and they got me in and repaired quickly. I was on my way again in less than a few hours! Everyone was professional and friendly! - Richard O.

These guys are great! They took great care of our trucks. They are very fair on price and really good at getting our truck back to us quickly. - Seth M.

Jeremy hooked us up to a code reader and set out in plain English our dilemma. We respect clear communication and great advice! We are grateful to Jeremy for his time with problem solving our road trip issue and for his thorough assessment of our needs. God Bless the beautiful, professional mechanics of Cheyenne, Wyoming! Thank you thank you

These guys are great. I needed a hard to find part while on vacation. And they made it possible for me to pick this part up on my way home after hours. At a great price

I have a 2000 Ford F-250 with a 7.3 powerstroke. I brought the truck in with a oil leak and it wouldn't start. So they diagnosed the problem and fixed it. They did very good work. Also they got it done very quickly. They have excellent customer service. I would highly recommend them to any diesel owner. Thank you for your hard work and good customer service. I really appreciate it.

Brought my truck in for diagnostic on an electrical issue, found things that I didn't even know could go wrong. Good people good customer service, fair prices. Don't care what anyone says I wont take my truck anywhere else!

Mr Diesel is a family run business with a very professional knowledgeable staff. George is the best Diesel mechanic in Cheyenne as far as I'm concerned I wouldn't let anyone in Cheyenne work on my truck except Mr Diesel. Best Diesel shop in Cheyenne very fast and friendly service from George, his wife and staff.

I don't normally do reviews but this place is amazing never had an issue always up front and tells you w hats going on and how much. Great prices and gets it done quickly. No bull just good guys telling you how it is and what you need to do thanks to them im back on the road

Great Service! George is friendly and will go the extra mile for his customers. If you live in the Cheyenne area and have a diesel pickup I highly recommend Mr. DIESEL!

Very knowledgeable and helpful, quick and quality work. Very Friendly. Great price.

Good people, Trevor is a knowledgeable tech and a good person to deal with.

Honest, efficient and at a fair price. Nothing worked on that wasn't needed.
