I'm a new customer. I was looking for a diesel shop to help me care for my F350 after the extended warranty that I purchased expired. I enjoyed talking to the folks there while the shop crew changed my oil, and I'm looking forward to working with these guys.

The staff here is knowledgeable and courteous. But most importantly, they are reliable and honest. No hidden charges or fee's. I've only trusted them twice with my truck to test if I would continue buisness with them. I think it's safe to say I've found my new home for honest and reliable diesel services.

Fantastic diesel shop in the North Texas area for all repairs & upgrades! They installed a FASS Titanium Signature Series fuel system on my '00 Ford F250 in a couple days! They had previously returned my daily driver back to roadworthiness with an entire A/C system, alternator, new batteries & connectors, the starter, and other wiring/electronic gremlins. I recommend them to everyone i know that need work done on their diesels

PowerFlo and the folks that run the show are really great. The Team does great work. The price may be a bit on the higher end, but you get what you pay for. They stand behind their work, provide strong recommendations, without unnecessary pressure or add-ons. HIGHLY recommend.

They were very professional and did a thorough job. Communication was constant as well as quick to respond with any questions that we had.
I would highly recommend them to any diesel owner needing service, maintenance or repairs.

Very straightforward, good work. Good value, much better than the dealer. They specialize in diesels and you need to make an appointment!

No one even comes close when it comes to honesty and quality of work that these guys do. Hard to find a diesel shop to trust, so I feel lucky to have found them. Don't hesitate to trust this shop! Thanks, POWERFLO!

Got my truck running, and did so in a timely fashion... especially considering Christmas and New Year's was involved

I've been a happy client for more than 10 years. These guys are not only the best diesel mechanics in town but they are the most honest. You will never be ripped off.

If you own a diesel truck, Powerflo Diesel is the best place to take your truck to. Honest and reasonable. Saved us a couple thousand dollars when one Ford dealership in Dallas wouldn't honor something under warranty. They went above and beyond and drove our truck over to Bob Tomes Ford in McKinney and they took care of the issue.
