How it All Got Started.


The owner of Maximum Diesels, Russ, started on a shoe string and now 8 years later he has a thriving business. With diesel running through his veins he knows diesel engines inside and out. Coming from a diesel tech background he has seen a lot of things that would make most men cry.

Russ and his dedication gave him the fuel, passion, and desire not to fail. Now he is a successful business taking care of his customers, doing what he loves doing best.
