JD had blogged about fuelly recently and I got interested, especially because I was, at the time, about to embark on a pretty long road trip. Its really pretty neat to see the fluctuations in the fuel economy (I wonder if there is a link with the Ethenol additive?) and compare to other people. It became a bit of a game for my boyfriend and I to write all the stats down at every stop. Awesomely enough, out in Montana they had a sticker on every pump stating the percentage of state and federal tax that was taken XD
I think my fuel economy is pretty good because, first and foremost, I have an efficient car. But I also keep its tires inflated, I never use the air con. and I try to keep it as well-maintained as possible.

Does anyone else use this?
