I have added a smaller version of the Feully "signature" banner (above) to the left-hand column of the blog. Fuelly is a social-media site designed to allow users to track their fuel economy over time, share that information, and trade fuel-saving ideas.
I've added every fill-up of my Scion to a Fuelly profile since I started driving it in July. Over 18 fill-ups, I'm averaging 32.5 miles per gallon. My best performance has been almost 36 mpg, back in the summer. I go about 300 miles between fill-ups.
