Send FuelFrog the miles you traveled on your last tank of gas, the price you paid, and the number of gallons of your next fill-up, and it will track your mileage. Once you've signed up for the service, it can keep tabs on your miles per gallon and how much you spend on gas. FuelFrog works best with Twitter, especially if you can tweet, as they say, from your phone right at the gas station. You punch in the numbers in order -- miles, then price, then gallons -- and send Twitter the text message.
