Nelson has been phenomenal every time we have used his services. He is very knowledgeable of the emission system/ aftertreatment whether is diagnosing or repairing the problem equipped with the most advanced diesel equipment and program. His cleaning machine is top notch and has provided the solution the owner op/ truck owner needs to keep this important system up to snuff without any agravant becoming a major and costly headache. With Nelson and Diesel Power X your truck will be in the best hands counting with a higher ethic and professionalism by your side. Absolutely recommended!!!

Great experience. No issues at all 5 plus stars.I Called Nelson the owner of diesel power x., and I explained my 2017 Freightliner Cascadia had the check engine light on, with Nelson being mobile he was able to meet me the very same day. Nelson was my diagnostic technician who explained everything so I could easily understand. Nelson found after a test drive that the downstream NOX sensor malfunctioned and needed to be replaced. After replacing I had no more issues, Nelson was very polite, on time and has done a great job diagnosing the problem. For what I have experienced with the DPF systems that it is a massive complicated issue, but Nelson the owner of Diesel Power x my DPF system was no match. I will always call him for all my diagnostic needs,Very happy to recommend.

Solved our problem. KW dealer took 6 hours and still didn t figure things out. Called Nelson and 1 hour later it was done. Nelson will be the 1st on my list if any after treatment issues and will be using his engine/after treatment cleaning services.

Nelson knows what he is doing when it comes to diesel emissions. He has worked on my truck a couple of times, and I am very pleased with the work he has done. He had fancy diagnostics tools and shows you precisely what s wrong with the truck, along with the available repair options and pricing. I highly recommend his service.

Nelson used the Diesel Force Treatment on my Peterbilt 579 yesterday. My system was showing high soot levels and requiring parked regen which did not work. After the treatment I notice a definitive difference in the way my truck is running. Can t recommend his service enough. Worth every cent!

New options for you to keep your truck on the road. Nelson is the person that opened my eyes to a cleaning service for your engine and DPF system. Keeping your truck in compliance with the epa and extending the life of your filters. Take the time and learn the options you have available talk to Nelson you won t be disappointed.
