20 Most Expensive States to Refuel Your Car

These are the 20 most expensive states for refueling your car right now.

Thinking about a summer road trip? Some states are more expensive than others. A major reason is the cost of gasoline, which has been rising steadily this summer after dropping during the first months of the year. Increased demand and reduced supply from overseas are partly to blame, experts say. New data from AAA found the national average for a gallon of gas sits around $3.828 as of the first week in August, and prices vary up to 70 cents depending where you live. These are the 20 most expensive states for refueling your car right now.

Gas in Pennsylvania will run you $3.908 for a gallon of regular, about eight cents higher than the national average. Why? "Some of the refineries in Texas and Louisiana had to shut down or reduce their production due to the heat," Alan Gin, an economics professor at the University of San Diego, told Fox 43 this week. A cutback in oil production by Russia and Saudi Arabia is also to blame.

In Alaska, the average gallon of gas is currently $4.466. "I don't expect any relief at the pump in the next few weeks," analyst Larry Persily told KTUU. "It's going to take either a lot [of] new supply that the market doesn't expect or lower demand to affect those prices at the pump. So it looks like Alaskans will head into the fall with prices higher than they want at the pump. But lower than they were at the height of the price spike last year."

Oregon
