Ram 3500 MPG test

^^^^ Honesty I don't have a problem with the fill technique that was used. I used to check my fuel economy on every tank with my 2011 Ford, filling that same method, and got very consistant results. As long as you fill using the same method at the beginning and end of your trip there shouldn't be a problem with their method. But, I am surprised at the difference. If it had been the other way ... ie, if the Ford had burned 30% more fuel than Ram, there is a very good chance I would end up with a goat in my garage. I would at least be doing my own mpg check before buying.
