I filled up on Wednesday. 557.9 miles on this tank, still pulsing and gliding. Worse yet, there's been a bunch of rain (which robs your momentum), two panic runs, and a dead battery.
10.298 gallons. That's 54.2 MPG! Better than last time, although I have NO idea how that happened. I've inspired coworkers to make their own attempts at fuel efficiency. Now I really need that bumper sticker.
