Track your MPG with Fuelly.com

A friend of mine showed me a great website called www.fuelly.com where you can keep track of your gas mileage and MPG online. After 2 fill-ups it will collect the data you input and calculate MPG. It has useful charts and the best part is you can compare with other owners who have the same year and model you have.

It's free to use so I recommend you check out www.fuelly.com. If you have an iPhone, you can put the data in right from the gas station from their website.
