CNN.com's biofuel road trip

Two fellows from CNN.com did an experimental road trip this summer in a truck outfitted for biodiesel consumption.

Cody McCloy and Brian Hardy drove from San Francisco to Atlanta in their newly purchased - yet old school - biodiesel vehicle (pictured right).

They mapped out biodiesel refilling stations ahead of time, but sometimes these stations wouldn't be open, so sometimes they needed to use regular diesel.

All in all they drove 4,189 miles, used 81.39 gallons of biodiesel, and 74.67 gallons of regular diesel.
