Testimonials

On 3/31/2026 Jarrell Wright had this to say:
Excellent help stop me from buying a bad truck

On 3/20/2026 john withington had this to say:
Supreme Diesel experience was amazing. The techs are extremely knowledgeable responsive and they do phenomenal work. My vehicle was slow sluggish and running rough, but since I got it serviced it has never run so good. If you have a diesel I strongly recommend that u have it serviced here. One of the few mechanics in Jacksonville that actually knows how to work on a diesel. The ford truck diesel dealer was never able to fix the issue for years, but Supreme Diesel did the first time I took it in.

On 3/6/2026 Keith Ague had this to say:
I needed some long overdue maintenance on my 2012 F350 6.7. I needed a new CCV box. These guys made room for me on short notice. They completed the work in just little over 1hour. There service charge was very reasonable. So reasonable I’m having both my front and rear diffs cleaned and refilled on my way back through. Highly recommend them.

On 2/23/2026 Christopher Kilpatrick (iStreamPS5) had this to say:
Victor and his team at Supreme Diesel went above and beyond to fix my truck. They expertly installed a new crate motor and towing transmission, and coordinated the warranty requirements through the manufacturers. They also corrected a few mistakes made by another mechanic. Victor and his Techs were extremely helpful in diagnosing the problems I was having and helping me find the best solution. I really appreciate the excellent communication and willingness to answer my many questions. My truck is now running phenomenally better.

On 2/2/2026 Jeremy McHenry had this to say:
My '22 Ram was running all sorts of jacked up, but Victor and the guys at Supreme Diesel Performance got it sorted out, and well ahead of the time I thought it would take. Great group of guys!
