U.S. gas prices rose to a national average of $4.29 a gallon Friday, October 23, as Brent crude briefly topped $117 a barrel. The increase interrupted a recent decline at the pump, although gasoline remained cheaper than a week earlier. AAA and federal energy data explain the mixed signals for drivers and fuel-dependent businesses.
Key Takeaways
- AAA placed regular gasoline at $4.2926 a gallon Friday, up from $4.2701 Thursday.
- The national average remained below its $4.3271 level a week earlier.
- Brent crude futures touched $117.45 before settling at $116.72 a barrel.
- California averaged $6.06 for regular gasoline, while North Carolina averaged $3.53.
- U.S. crude inventories fell by 3.1 million barrels in the latest weekly federal report.
Gasoline prices moved higher on Friday just as the international oil benchmark recorded its strongest weekly gain since early September. Brent futures rose 6.2% for the week, according to Dow Jones Market Data, reflecting market concerns about further interruptions to Middle Eastern energy supplies.
Yet the two markets have not moved in lockstep. Retail gasoline prices reflect fuel that has already been refined and distributed, while the latest crude price affects the cost of replenishing supplies. That distinction helps explain why a sharp move in oil futures can coexist with a smaller change at neighborhood stations.
U.S. Gas Prices Rise Despite Cheaper Winter Fuel
AAA’s Friday reading represented an increase of about two cents per gallon from Thursday. The national average was still roughly three cents below the previous Friday and 18 cents below the level one month earlier, showing that the latest daily increase has not erased October’s broader retreat.
The year-over-year comparison tells a different story. Regular gasoline averaged $3.0713 a gallon on October 23, 2025, according to AAA. At this Friday’s average, buying 15 gallons would cost approximately $64.39, versus $46.07 a year earlier. That is about $18.32 more for the same quantity of fuel.
In a Thursday update, AAA attributed a six-cent weekly decline to the transition toward winter-blend gasoline, which is generally cheaper to produce than summer-grade fuel. The organization also said that “high crude oil prices are preventing steep declines at the pump.”
State averages show how uneven the price picture remains. AAA listed California at approximately $6.06 a gallon and North Carolina at $3.53 on Friday. Washington was near $5.33, Texas averaged $3.75 and Georgia stood at $3.69.
Some Midwestern markets experienced notably larger overnight increases. Ohio rose about 29 cents, from $4.08 to $4.37, while Michigan increased about 16 cents to $4.77. Such changes are visible in AAA’s daily averages, but the data alone do not establish that Friday’s crude rally caused them. Regional fuel supplies, pricing cycles and refinery conditions can also matter.
Brent Crude’s $117 Peak Adds Pressure to Seasonal Relief
Brent crude futures reached an intraday high of $117.45 on October 23, their highest level since late April, according to Reuters. The benchmark settled at $116.72, up $3.55, or 3.1%, for the session. The rise followed renewed concern about the stability of energy supplies from the Middle East.
The latest advance follows earlier oil prices above $100 in September, when the global benchmark had already drawn attention to transportation and industrial fuel expenses. Still, a $117 barrel of crude does not translate directly into a specific gasoline price.
The U.S. Energy Information Administration identifies four main elements of the retail gasoline price: crude oil, refining, distribution and marketing, and taxes. In its latest available monthly breakdown, for May 2026, crude accounted for 51.9% of the average retail price. Refining represented 21.7%, distribution and marketing 14.8%, and taxes 11.5%.
Those shares describe May, not Friday’s pump prices. They illustrate why the cost of crude is important without being the only factor. The EIA also notes that retail prices often adjust after wholesale prices, creating a lag when crude or gasoline spot markets move abruptly.
Winter fuel offers another offset. Because winter-grade formulations are generally less costly to produce, the seasonal switch can reduce retail costs even when underlying crude becomes more expensive. How long that offset lasts depends on local fuel supply and the pace at which wholesalers and stations change their prices.
Diesel Prices and Declining Stockpiles Add Business Pressure
Diesel remains considerably more expensive than it was a year ago. AAA listed a national average of $6.3172 a gallon Friday, compared with $3.6315 on October 23, 2025. That difference matters for trucking fleets, delivery operators, agricultural businesses and other companies that use diesel-powered equipment.
Businesses do not necessarily pass every fuel increase directly to customers. Contracts, fuel surcharges, vehicle efficiency and competition affect how operating costs appear in freight charges or retail prices. The same higher oil benchmark can therefore have different consequences across industries.
Concern about refined-fuel availability was already reflected in an October 2 coordinated diesel release plan. The International Energy Agency subsequently said members were working to accelerate remaining emergency stock releases, including more than 20 million barrels of diesel as soon as possible. Those plans do not establish what prices will be at individual U.S. stations.
Domestic inventories provide additional context. In its October 21 report covering the week ended October 16, the EIA said commercial crude stocks declined by 3.1 million barrels to 412.5 million barrels. Gasoline inventories fell by 3.0 million barrels and stood approximately 5% below their five-year average for the time of year.
Refineries operated at 93.4% of capacity during the reporting week, and gasoline production averaged 9.8 million barrels per day. These figures predate Friday’s oil-market rise and cannot measure its immediate effect on supply. They nevertheless document the operating and inventory conditions against which the latest U.S. gas prices were recorded.
Frequently Asked Questions
How much were U.S. gas prices on October 23, 2026?
U.S. gas prices averaged $4.2926 a gallon for regular gasoline, according to AAA. That was about two cents higher than Thursday but about three cents lower than a week earlier.
Why did gasoline rise while winter fuel became cheaper?
Winter-grade gasoline generally costs less to produce, which helped lower the national average earlier in the week. Higher crude costs can offset some of that benefit, although changes do not reach all stations at the same time.
Which states had the highest and lowest prices?
AAA listed California at approximately $6.06 a gallon and North Carolina at $3.53 on October 23. State taxes, regional fuel specifications, distribution costs and refinery conditions contribute to price differences.
What do higher diesel prices mean for businesses?
Diesel averaged about $6.32 nationally on October 23, well above the year-earlier level. Higher fuel bills can affect shipping and operating expenses, but their effect on customer prices depends on each company’s costs and contracts.
