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.

We are from Boise idaho and are truck broke down we were actually towed to the Dodge dealer in laramie and decided to have it towed back to Cheyenne to Mr diesel . My husbands transmission was toast. I can't express enough how honest, fair priced and how nice they were to us. Thank you and honestly if you are from out of town and looking for a great mechanic I wouldn't go anywhere else!!! Thanks again for getting us back on the road to get back home.

They repaired my truck in one day. I broke down in Cheyenne and called them before close and they took one day as they told me they wood. Very knowledgeable, very helpful, and they give military discount. They explained all the work they did and had shown me all the parts that were removed and why they were replaced, because I asked. Should have taken two days but because I was in transit he had two mechanic working it to get it done and get me back on my way. I recommend them whole heartedly. Very honest and down to earth. The owner is really easy to work with.
