Unfortunately, I'm not going to be able to put down all highway tanks like he does. My work commute is 3.2mi of city driving on a cold engine. 
I'd be interested to know which mods got him that huge increase. I'm considering fiberglassing a belly pan as well. |
Don't dispair. I usually go 50% highway, but today I took a more rural route with a few stops. Although I had to stop 4 or 5 extra times, I was able to go a little slower and take advantage of more coasting opportunities that would have been useless at a higher speed. The difference was a 5 mpg increase! I will continue to test this route for the next few days.
Never give up!
