What kind of mileage are you getting? Do you really know? Fuelly is the brain child of two northwest locals in Oregon (where lots of great sustainable ideas seem to come from these days), Matt Haughey and Paul Bausch. The website came together in a little over two weeks and was initially conceived as a simple MPG history calculator application. It didn’t take the two long to realize that Fuelly can be accessed anywhere you’re willing to call up the website on your mobile phone. By tracking your miles you may find that there are a number of different small things you can do to increase your mileage before you find yourself at the next gas station. Whether or not you register for Fuelly, you can consider these three tips we pulled off their website:

50/50 Rule – As the television show Mythbusters has proven – when traveling under 50 MPH it is more fuel-efficient to leave your windows down and your AC off. When traveling over 50 MPH it is more fuel-efficient to have your AC on and your windows up.

Why charge a red light? – Look ahead, if you see a light is red just coast. You’re not getting through the intersection until the light turns green anyway so why rush?

Cup of Coffee on Dashboard – Pretend you have a cup of hot coffee on the dashboard. Accelerate and decelerate in a manner that would not make the cup of coffee spill.
