What Our Clients Say
I love what I do keeping you guys rolling making money! My goal is to keep your down time to a minimum and I do whatever I can to get you back on the road as quickly as possible! You will always see me back and forth on I40 keeping fleets and owner operators rolling.
I can’t give Steve at DPF doctors shop enough praise on how fast and quick he was to get me and my military load back on the road. Loves created a problem and he repaired it within minutes of diagnosis. Loves tried for hours to see what problems they created after a simple PM. Steve figured it out and got me going immediately. Thanks Steve and you are my go to guy in Albequrque area. Don’t trust Loves! Especially for mechanical work
This shop (Steve) is the best around for quick repairs right off I40 east of Albequrque. Called him late in afternoon and he did not hesitate to meet me. Figured out my problem that was created by Loves truck stop. Loves after second attempt to fix the problem they created told me to tow my truck back to their shop. Thank God we found DPF doctor and he figured it out within minutes of the damages and problems that Loves did to my truck. Had me back on the road within an hour. Highly recommended him for cars or Semis! He is an all around mechanic and does you right on work and price!!!!
Steve is an awesome guy,we were stuck in Albuquerque and he looked over our truck, corrected mistakes that had been done by previous mechanic and we were up and running. He is the guy to see if you in the area!!
He got to me quick, was very knowledgeable and really reasonable priced. Highly recommend.
Hey Steve,
Thanks for being so professional and right guidance. He is the best mechanic you should talk and do business. He even helps you over the phone to get you running.

Steve was very professional he was on site in less than an hour diagnosed and repaired the truck in under 30 minutes I would recommend him to anyone
I could go on and on about the integrity, patience, and pure dedication of Steve and how he got me up and running but this review would be about five pages long. When I tell you this man is worth his weight in gold, I mean it. We had a very complex issue with our Mack and Steve answered the phone in the dead of night, drove two hours to my truck, and was there for about five hours working non stop. He made it right, and when I say he was BEYOND generous with his time and price, I mean it. This man is an absolute treasure to the field and we have now established a lifelong professional relationship with him and his business. He is the best of the best out there. Call him and he’ll get the job done RIGHT and FAIR. Thank you, Steve. Godbless
Steve is the mechanic people dream about. We’ve never owned a diesel, and Steve had the knowledge, character, wisdom and people skills to know exactly what to do. Im 60 years old and I can say in all my years, all the states my wife Kayla and I have been in, this is the best mechanic, person, individual you will ever find. There is none better.
Thank you Steve,
Eric and Kayla

Very helpful and very nice service . Steve is very helpful and nice person .
Honest and highly knowledgeable. Great service and communication, got to us right after we had called him and we were back on the road the same day. Thank you Steve!
I can’t say enough good things about this roadside truck repair service. They were fast, professional, and truly saved the day when my rig broke down miles from the nearest town. Within 30 minutes of my call, a technician was on site with all the tools and parts needed to get me back on the road.
Called Steve and advised of the issues we were having with our Volvo tractor. he provided good suggestions and came out quickly. When he determined he was not able to correct the issue due to blocked up filters he suggested another company that could assist and did not charge for the roadside service. This man and company is very honest and you do not come across this often in the trucking industry. We will defiantly use him again and spread the word.
Replaced my DPF pump and Doser on Sunday evening. Great guy, highly recommend from DPF related issues on semi trucks.

I’m pretty sure Steve was dropped straight out of heaven to be our guardian angel when we broke down in the middle of nowhere pulling our travel trailer. He drove out to the rest area where we were stranded on a Saturday afternoon, diagnosed our issue and provided a temporary fix so we could drive in to Moriarty. He checked up on us and provided helpful tips on the area until he could source the part we needed on Monday morning, when he was able to do the repair and send us on our way. Seriously can’t believe our good luck to have broken down exactly where we did so we could connect with Steve. If you’re ever in or around Moriarty and need a mechanic, do yourself a favor and call Steve!
Amazing service! They works fast, honest, and with real heart. Fixed my truck quickly and treated me with respect. Hard to find service like this these days. Highly recommend DPF Doctors!

Dude went out of his way to help my driver get back to KC. Did a bang up job and has a honest quality you don't see much of anymore.

Steve was so kind & helpful! He didn’t have the tires we needed, but went out of his way to call around & find a shop that would be able to help us. Just an all around good guy, 10/10 recommend!!
I can't express enough how thankful we are for Steven Iler's incredible service. Last night, when every other shop was closing, he didn't hesitate to meet my girlfriend at 6 PM at his shop to address a loose plastic part on our vehicle. Being stranded with our baby was a huge worry, but he quickly diagnosed and fixed the problem, getting us safely back on our way in no time. His willingness to help in this way was truly exceptional and deeply appreciated. I highly recommend for any mechanic services you need.
On short notice, Steve helped us out; he diagnosed the problem and resolved the problem with ease. Friendly, knowledgeable, and located in a convenient place, DPF Doctors is close to I40 and NM 41… whether you need diesel truck help or regular car maintenance, give Steve at DPF a ring!

Thanks Steve!
Steve is great to work with! He got my car up and running faster than his initial estimate and the car is still running great! Thank you so much!
We were forced to stop in Moriarty, NM due to DPF/SCR Codes and were lucky enough to have stopped in the right town. Steve really does have a PHD in this. We're grateful that he was recommended to us from a local mechanic shop in town. Steve is very insightful, informative, and most importantly honest. Helped us out with our SCR issue and got us back on the road the same day. He really does care about you and your business and does everything in his power to help. We run across 40 often and glad we now have Steve's number. Can't imagine sending my truck anywhere else if I have ever issues again. Thanks Steve!
An amazing Mechanic, he's good at what he does and he does his best to compromise with you about pricing
This is the best place to go if you are in need of dpf repair. These guys know what they are doing, do it quickly and do not over charge you for their work. They will travel to you, even if you are far away from Moriarty. Highly recommended. Great guys!
I’m a repeat customer. Won’t take my trucks to anyone else. Steve and his partner are amazing at what they do and will not over charge you! Highly recommend.
Amazing customer service! Steve is extremely knowledgeable regarding truck and automotive issues. The most trustworthy company I’ve ever had the pleasure of doing business with. I highly recommend DPF Doctors.
