GasBuddy

One way to save money on gasoline is by using GasBuddy. This website and free mobile app allow travelers to research gas prices. You'll see nearby gas stations and the per-gallon price at each place, so you can quickly compare and choose a convenient and affordable gas station to fuel up.

You can also use the trip cost calculator to estimate your fuel costs before you leave so you know how much money to include in your vacation budget for this expense.
