I have been using your company for a few years and greatly appreciate your services. Your reports help me monitor my collection of military vehicles and the truck I use daily. I find your comments on the reports very informative and easy to understand. So far your company has helped me save money in my F350, by not having to change the oil every 3000 miles. Being that the motor is a 7.3L, it is not cheap to change the oil if it does not require it. Also I wanted to note that the deciding factor for me to use your company was your FAQ. I must admit that I found that to be quite hilarious and it shows that you have a great company and a great staff.
