Best place in town for diesel performance and repair

— Andrew M.

My Duramax was acting up about restricted fuel coming back from a long trip pulling a toy hauler. Took it here for diagnostics, Mike asked to look at first and recommended replacing the fuel filter with a better brand. That seemed to have worked. They didn't try to charge me a dime! I appreciate the honesty!

Mike and Mark at 23 Diesel were some of the most acceptional mechanics I’ve worked with. I brought in my Mercedes Sprinter Van and had them do some work to it. They were extremely knowledgeable and very patient. It takes a specialized mechanic to work on this rig and I wish I had found these guys sooner. There experience with diesel engines is unmatched in the grand valley. I would highly recommend these guys to anyone! They were also super honest about their work which is hard to find when it comes to a mechanic.

Mark and Mike are awesome guys. I went to the shop after looking for someone i could trust with my modified diesel truck. I believed i was having issues with my injectors. With that being a very spendy repair bill i was looking for someone who would give an honest answer and not just look at me as a dollar sign. These guys got my truck in and used the proper diagnosis tool to give me the news I was looking for. No injector issues!!!! Lets just say these guys have earned my business and will recommend them to anyone who has a diesel vehicle. Thanks again Mark and Mike.

Our truck broke down while traveling through town on vacation. These guys went above and beyond to get the truck running again. If I lived closer I would use them for all my truck needs!

Found the last place I will ever need to go for my diesel needs. Mark & Mike are both knowledgeable and happy to answer questions. Great prices as well!. I really can't say enough about this place. If your going elsewhere your paying more and not getting it done right.
