I had a wildland fire team traveling from Colorado to California for a fire activation and they had some car troubles along the way. They chose to stop at J&S Diesel to have it looked at and once diagnosed James called me up. I have been a professional mechanic for over 20 years, and I could tell very quickly that James knew what he was talking about and that I could trust him to take care of us. His shop was able to do some significant repairs in a very short time and verified the repairs on a 70-mile test drive (I don't believe most shops would go to this extent). I was very impressed with the professionalism and expertise of J&S Diesel billing was straight forward and well defined. I would recommend them to anyone needing service for their diesel vehicle. Thanks again James.
