Jason knows his stuff. Most honest guy, easy to talk to, gets prob fixed right; what more can I say.

I brought my diesel in and it was running like crap. By the time I got it back, it felt like new... Actually better than new because of a slight upgrade. It has never been so powerful and fun to drive!

Besides, it has to be a five star because he has tons of work and people who go to him, that's based on the fact that he's always got a full lot of vehicles for him to work on. But he moves through quickly; I never have a long turnover, and one of my issues was not so small.

I just had my Cummings diesel repaired at xtreme diesel and could not be more satisfied. Jason is a very hard-working man and spent many hours diagnosing my problems. He was very fair with his prices and time.

I would never go anyplace else, if you want honest repair this is the place to go. As you probably know there are very few places to get diesel repair. The other company that's been in Chico for quite some time on Highway 99 has a very bad reputation. My personal experience with the other company motivated me to seek out a new repair facility. My grandson recommended xtreme diesel, he is much smarter than he looks.

Thanks Xtreme diesel - YOU ARE THE BEST!
