Official EIA weekly retail prices — the EIA surveys selected large states plus the five PADD regions, not all 50 states. See the full gas-prices page, prices by year, and why prices differ.
Among states the EIA surveys weekly, California has the most expensive regular gasoline at $5.43 per gallon (week of 2026-08-10), versus a national average of $4.01. Texas is cheapest at $3.51.
Three main reasons: state fuel taxes (from about 9¢ to over 68¢ per gallon), fuel specifications (California and some metros require costlier special blends), and distance from refining centers — Gulf Coast states sit next to the refineries, while the West Coast is an isolated market where outages spike prices.
No — the EIA's weekly survey publishes a subset of large states plus the five PADD regions; that's what this table shows, from the official government series. For daily crowd-sourced estimates covering every state and county, AAA and GasBuddy are the standard complements.
