California Gas Prices Hit $6.02 a Gallon as the National Average Tops $4.29

• AAA’s national average for regular gasoline reached $4.2892 a gallon on October 25, up from $3.1156 a year ago, a jump of roughly 38 percent.
• California set a new state record at $6.0188 a gallon, while North Carolina sells the cheapest gas in the country at $3.4806.
• Crude oil climbing back above $88 a barrel, combined with rising gasoline demand, is pushing pump prices higher heading into November.

A Gallon of Regular Now Costs 38 Percent More Than Last October

Drivers paid $4.2892 a gallon for regular gasoline on October 25, according to AAA’s daily Fuel Gauge Report. That figure sits a few cents below the $4.36 average AAA recorded a week earlier, but it still towers over the $3.1156 a gallon drivers paid at this time last year. The gap adds up to roughly $17.60 more for a 15-gallon fill-up than the same tank cost twelve months ago.

California logged a fresh record of its own. The state’s average hit $6.0188 a gallon, the highest figure AAA has posted for California this autumn and more than $1.70 above the ten-state sample’s next-priciest market. For a driver filling a 15-gallon tank in Los Angeles or Sacramento, that works out to roughly $90 at the pump, more than double what a driver pays for the same fill-up in several Southern states.

Why Prices Climbed Back Up This Month

AAA’s own account of the market, published October 8 under the headline “Pump Prices Remain at Record Highs for Autumn,” points mainly to crude oil. West Texas Intermediate settled at $88.28 a barrel after a $1.16 drop in a single session, still well above the price levels that held through most of the summer. Gasoline demand climbed from 8.68 million barrels a day to 8.76 million, a notable move for late in the year when demand typically cools. At the same time, gasoline production slipped from 9.46 million barrels a day to 9.34 million, and crude oil inventories fell by 3.2 million barrels to 424.1 million barrels, a level AAA puts at about 1 percent above the five-year average.

Put together, those four numbers describe a market where buyers want more fuel than refiners are turning out, right as the raw material to make that fuel gets more expensive. AAA also flagged storm activity along the Gulf Coast as an ongoing risk to refinery output, a hazard that shows up most autumns and can push prices higher again with little warning.

California’s Price Problem Goes Deeper Than Crude Oil

California’s $6.0188 average did not appear out of nowhere. Refining capacity in the state has been shrinking for more than a year. Phillips 66 closed its Los Angeles refinery in October 2025, and Valero has scheduled its Benicia refinery to close in April 2026. A University of Southern California Marshall School of Business analysis estimated those two closures alone could cut the state’s in-state refining capacity by as much as 21 percent between 2023 and April 2026. California typically has to lean on refiners along the Gulf Coast, and in some cases as far away as South Korea and China, to cover any shortfall, and that extra shipping distance adds cost that state drivers absorb at the pump.

California’s state gasoline taxes and its cap-and-trade and low-carbon fuel standard programs add a further 70 to 90 cents a gallon on top of the national baseline, according to figures the California Energy Commission has published in past market updates. Combined with tighter refining capacity, that structural gap is the reason California drivers have paid well above the national average in nine of the last ten years, and why a $6 gallon no longer counts as an anomaly in the state.

The Other States Paying the Most

California was not alone at the top of AAA’s list. Hawaii followed at $5.6510 a gallon, a price that reflects the cost of shipping fuel to an island market with no in-state refining of its own. Washington came in at $5.3047, and Nevada at $5.2984, both states that buy a share of their gasoline from California-linked supply chains and inherit some of that market’s volatility. Illinois rounded out the top five at $4.8851, driven by a combination of state fuel taxes and seasonal blend requirements around Chicago.

Where Gas Is Still Cheap

North Carolina sits at the other end of the scale, at $3.4806 a gallon, the lowest average AAA recorded among the 50 states on October 26. Georgia followed at $3.6491, Texas at $3.7101, South Carolina at $3.7624, and Louisiana at $3.7770. All five states share two things in common: comparatively low state gasoline taxes and proximity to Gulf Coast refineries, which cuts out the transportation costs that inflate prices in places like Hawaii and the Pacific Northwest. A driver filling a 15-gallon tank in Raleigh pays about $52.21, versus roughly $90.28 for the same fill-up in California.

What To Do If You’re Paying More at the Pump

Drivers who want to soften the hit have a few concrete options. Price-tracking apps such as GasBuddy and AAA’s own mobile app crowdsource station-level prices in real time and routinely surface swings of 20 to 40 cents a gallon between stations just a few miles apart. Grocery store fuel rewards programs, including those run by Kroger and Safeway-affiliated chains, can knock 10 cents or more off every gallon when a driver has built up enough points from a weekly shop. Warehouse clubs such as Costco and Sam’s Club typically price several cents below the street average at their attached fuel stations, though membership fees need to be weighed against the savings for drivers who do not already belong.

Timing changes the math too. AAA’s historical data shows prices tend to dip early in the week and climb heading into weekends and holidays, when demand rises. Drivers planning a long trip can check AAA’s state-by-state averages before departure to route through cheaper markets where the drive allows for it, and topping off a tank before crossing into a higher-tax state, such as California or Illinois, can save real money on longer trips.

Why This Breaks the Usual Autumn Pattern

Pump prices normally fall between Labor Day and Thanksgiving. Refiners switch over to cheaper winter-blend gasoline, road trips taper off once school starts, and cooler weather trims the miles Americans drive on an average week. AAA’s own description of this month’s numbers, under the headline “Pump Prices Remain at Record Highs for Autumn,” spells out why this year looks different: even with the seasonal switch to winter-blend fuel, the national average is still running at levels AAA says it has not previously recorded for this point in the calendar. Instead of the usual fall dip, drivers are watching crude oil and demand both move the wrong way at once.

The effect reaches well beyond the pump. Diesel tracks a similar pattern to gasoline, and higher diesel costs get passed through the supply chain into the price of groceries, furniture, and anything else that arrives by truck. A trucking company running a fleet of long-haul rigs can see its monthly fuel bill swing by tens of thousands of dollars when diesel moves the way gasoline has moved this fall, and much of that cost eventually lands on store shelves rather than staying with the carrier.

Commuters thinking about a switch to an electric vehicle have a rough yardstick to work with. At the current $4.2892 national average, a gasoline sedan rated at 30 miles per gallon costs about 14.3 cents per mile to fuel. A comparable EV charging at home on a typical residential electricity rate of roughly 16 cents per kilowatt-hour, and averaging 3 miles per kilowatt-hour, costs closer to 5.3 cents per mile. That gap widens further for drivers stuck paying California’s $6.0188 average, where the same gasoline sedan runs about 20 cents a mile. Public fast chargers typically charge two to three times the residential rate, narrowing that gap, but drivers who can charge at home still come out well ahead of what they would spend on gasoline at today’s prices.
