Why is gas so much more expensive in California than in Georgia?
On October 12, 2026, a gallon of regular cost $2.503 more in California than in Georgia, so California's average was 65.8% higher [1]. At those averages, 15 gallons of regular cost $57.08 in Georgia and $94.62 in California [1].
The U.S. Energy Information Administration (EIA) lists the main reasons pump prices differ by region: state and local taxes, the distance from refineries and pipelines, supply disruptions such as refinery outages, local competition and operating costs, and environmental programs that require special fuel blends [4]. For California it points to a distinct gasoline blend made by relatively few refineries, stricter reformulated-gasoline rules and a higher gasoline tax than most states; when a refinery has problems, supply from other regions can take a long time to arrive [4]. The ranking shows a clear regional pattern: the ten cheapest states are in the South and the Midwest, and the six states at $5.00 or more are the three West Coast states plus Hawaii, Alaska and Nevada [1].
On October 12, 2026, regular gas ranged from $3.805 a gallon in Georgia to $6.308 in California, and the U.S. average of $4.356 was 41.3% higher than a year earlier.
How much have gas prices risen in a year?
Every state's average for regular was higher on October 12, 2026 than a year earlier. The national average rose from $3.083 to $4.356 [1]. The increase ranged from 21.6% in Washington and 22.2% in Oregon to 59.5% in Michigan, where regular rose $1.737 a gallon to $4.656 [1][5]. Oklahoma (+55.8%), New Mexico (+54.4%) and Wisconsin (+52.5%) followed [1].
Because the West Coast was already expensive a year ago, its percentage increases were the smallest: Hawaii rose 25.4% and Alaska 29.9% [1]. That narrowed the gap in percentage terms, but not in dollars: California rose $1.645 a gallon, more than any state except Michigan [1].
The last week was calmer. The national average for regular fell 0.9 cents from October 5 to October 12, 2026 [1]. Michigan (+20.0 cents) and Indiana (+16.6 cents) had the largest weekly increases, while North Carolina and Utah fell 11.4 cents each [1].
What about premium and diesel?
The national average was $5.246 for premium and $6.266 for diesel on October 12, 2026 [1]. Diesel showed the sharpest rise of any grade: up $2.60 a gallon, or 71%, from $3.665 a year earlier [1].
- Cheapest diesel: Texas ($5.668), Georgia ($5.726) and South Carolina ($5.770) [1].
- Priciest diesel: California ($8.380), Washington ($7.276) and Hawaii ($7.211) [1].
- Cheapest premium: Texas ($4.682), Georgia ($4.686) and Missouri ($4.718) [1].
- Largest premium markup over regular: Michigan ($1.227 a gallon) and Wisconsin ($1.175); the smallest was California's ($0.413) [1].
How we ranked
The ranking uses DataPorium's daily local gas prices: average retail pump prices in US dollars per gallon, updated daily, for the US, every state and DC, their metro areas and counties [1]. States are ranked by the average price of regular gasoline on the newest day in the data, October 12, 2026, which was the price date for all 51 areas. The 1-week, 1-month and 1-year changes compare that day with the same series one week, one month and one year earlier. This daily series is separate from the weekly government survey of retail prices and is not combined with it. State pages on DataPorium also show the cheapest and priciest county in each state, for example Georgia, California and Michigan [2][3][5]. The full daily series is on the DataPorium gas prices page [1].
