The latest online app to help drivers track fuel economy comes from Moblu. The site asks for your vehicle’s year, make and model then requires you to create a user name and password.
Where, you might be asking, does the social networking come in? Moblu uses your Twitter user name (no Twitter password required) to share your mileage with other Tweeple. Moblu users can record events that might affect gas mileage, like “Changed Tire Pressure” or “Lots of Highway Driving.” You can also record a fill-up, calculate mileage for a road trip, and find fellow Moblu users on the site.
Clicking on “My Garage” shows fellow Moblu cars, with actual mileage, trends, and number of fill-ups. You can choose to follow anyone who looks interesting, or keep tabs on your friends’ fuel economy.
