Hey everyone. I bought myself a brand new 2012 Passant TDI 8 days ago. I remember seeing the commercial on TV stating that you can drive a TDI from Chicago to New York on one tank so I figure that I am going to test this out. My wife and I are going from Maryland to Chicago and plan to document the trip for kicks and to see how well my new car can hold up to this. I plan to top off the tank before heading out, mark our exact driving path, compare the cars "Trip" miles to "mapquest" and "google maps". I am going to list a few more things that I plan to keep track off and will even make a movie. What I want to know from you guys is simply put... Is there anything you guys suggest that I should keep track of as well or something I haven't thought of yet?
