About these gas prices
These are average retail prices per gallon, including taxes, from the U.S. Energy Information Administration (EIA) weekly survey of gas stations. The EIA publishes new numbers every Monday for the nation, major regions, nine states and ten large cities.
Why gas prices differ by state
- Taxes – state gas taxes and fees vary widely.
- Fuel blends – some states, like California, require special cleaner-burning blends that cost more to make.
- Distance from refineries – areas far from refineries and pipelines pay more to transport fuel.
- Crude oil prices – the largest single factor in the price of gasoline.
