my best mileage was 498.2 miles....today hit 225 at the first quarter mark....hoping to pull close to 400 miles out of a half a tank....definitely hit over 300miles...which pushes me well beyond my best mileage and will push me deep into the 50+MPG range(my goal is to hit 50 with an attempt to hit 60mpg...hit 48.2mpg so far.....)
