Oklahoma
> Regular gas price per gallon: $3.00

> Operating refineries: 5 (tied for 6th highest)

Oklahoma is one of the nation’s largest oil producers. The state has five operating oil refineries and can produce nearly 509,000 barrels of oil a day — both among the highest figures for any state. Nationwide, Americans spend an average of 48.8 cents a gallon in taxes. In addition to being a key oil producer, Oklahoma is also one of the largest natural gas producers in the United States.

Texas
> Regular gas price per gallon: $3.02
> Gas taxes per gallon: 20 cents (tied for 12th lowest)
> Number of operating oil refineries: 26

According to the Energy Information Administration, Texas has the most oil refineries of any U.S. state. Paired with a state tax rate of 20 cents per gallon, state gas prices have been typically below the national average. The relative cost of transportation in the state is among the lowest in the country.

Arkansas
> Regular gas price per gallon: $3.01
> Gas taxes per gallon: 21.8 cents (16th lowest)
> Number of operating oil refineries: 2

The two refineries in Arkansas process about 90,500 barrels of gulf coast West Texas Intermediate crude oil per day, likely contributing to the low gas prices in the state. Another reason for the state’s low gas prices can also be its relatively low taxes on gasoline.
