Well I got back from my road trip (Chicago to northern Florida). The best I was able to get was 14.48mpg. I filled up in Cobb county Georgia after getting through the mountain area of Tennesse/Northern Georgia with Shell 87, I proceeded to maintain speeds between 70-80mph with a gentle/steady pedal, I was also running the AC.....when I got to around 3/8 of a tank we stopped for something to drink along with a bathroom break, I topped off and got my results. The rest of my fill ups netted me anywhere from high 12's to upper 13's depending on overall speed and whether the land was flat..... going through the mountains really sucks up the gas. There is not a doubt in my mind if someone kept is at 65 or less that you could easily see 16+ I just cant drive that slow
