Gasbuddy.com makes finding cheap gas easy. Select a location, and the site will pull up the 15 highest and lowest prices in the area, “as reported by 500,000 site regulars.” You can even search by station.
Cost2drive.com features a “Galculator” to help motorists calculate driving costs. Enter a starting point and destination, along with your car’s year, make, and model. The site will then determine gas costs, total distance, driving time, gallons of fuel used, and “even your trip’s carbon footprint.”
TripAdvisor.com/tankofgas “answers one basic question: Where do I go from here?” Enter a starting place and choose one-quarter, one-half, or a full tank of gas. The system searches TripAdvisor’s reviews of hotels, restaurants, and other destinations for suggested stops—including “some obscure and surprising choices.”
