10 States Where Gas Is Most Expensive -- and 10 Where It's the Cheapest

Where you live can have a significant impact on how much you pay for a gallon of gasoline. Drivers in the 10 states with the highest gas prices spend an average of $0.36 per gallon more than the national average of $2.56 a gallon, according to the latest data from AAA. While that might not seem like a lot, it adds up. For perspective, the typical American driver uses 656 gallons of gas per year, which means those drivers are paying about $240 more per year to fill up their car. Meanwhile, motorists who live in the 10 states with the cheapest gas are saving an average of about $400 per year compared to those in the most expensive states.
