A weekly fill-up that cost about $52 in January now runs nearly $64, and in California it is closing in on $86. The national average price of regular unleaded gasoline has climbed to $4.56 a gallon, according to U.S. Energy Information Administration data for the week ending May 5, 2026. It is the first time the figure has topped $4.50 since the summer of 2022. In California, drivers face a $6.16 average, roughly 35 percent above the national number and enough to push a 14-gallon fill-up past $86.
The last time prices were this high nationally was June 2022, when post-pandemic demand collided with supply disruptions from Russia’s invasion of Ukraine and pushed the average to about $5.01 a gallon. The forces behind this spike are different, but the timing is just as unwelcome: millions of Americans are mapping out summer road trips right now.
Why prices are climbing now
The EIA’s Weekly Petroleum Status Report for the week ending May 1, 2026, shows gasoline inventories falling for several consecutive weeks while refinery utilization rates have bounced around rather than ramping up steadily. Shrinking stockpiles without a reliable production increase is a recipe for higher retail prices, especially heading into peak driving season.
Crude oil is the single largest ingredient in what consumers pay at the pump, typically accounting for more than half the retail price. West Texas Intermediate crude has hovered near multi-month highs through the spring of 2026, supported by OPEC+ production discipline and steady global demand. When the raw material costs more, refiners pass that cost forward.
Seasonal mechanics compound the problem. Every spring, refineries shut down units for planned maintenance, known as turnarounds, to switch from winter-grade to summer-blend gasoline. The summer formulation is more expensive to produce and is required by the EPA to limit smog-forming emissions. That transition temporarily pulls refining capacity offline and raises production costs at the exact moment demand starts to pick up.
Why California is so much worse
California consistently sits at the top of the national price charts, and the current $6.16 average is no exception. The EIA’s regional fuel tracker shows the state running well above every other region, a gap driven by structural factors that have little to do with global oil markets.
Taxes are the first layer. California’s combined state excise tax and fees on gasoline rank among the highest in the country, according to the American Petroleum Institute’s state tax tracker. The state’s cap-and-trade program for carbon emissions adds further cost to fuel production and distribution.
Then there is the refining bottleneck. California mandates a unique, cleaner-burning gasoline blend that only a handful of in-state refineries produce. When one of those facilities goes down, whether for scheduled maintenance or an unplanned outage, there is no quick way to bring in replacement supply from Gulf Coast refineries because those plants do not make California-spec fuel. That isolation makes the state’s market far more volatile than the national average suggests.
The result is a price premium that persists year-round but widens sharply during supply disruptions. The EIA’s latest data does not specify which California refineries may be offline right now, so it is not yet clear how much of the $6.16 average reflects routine spring turnarounds versus unplanned problems.
What this means for household budgets
The math is straightforward and unpleasant. At $4.56 a gallon, filling a midsize sedan with a 14-gallon tank costs about $63.84. A household that fills up once a week is spending roughly $255 a month on gasoline, up from about $210 when the national average sat closer to $3.75 earlier this year. In California at $6.16 a gallon, that same weekly habit runs closer to $345 a month.
Those increases hit hardest for lower-income households and workers with long commutes who have few alternatives to driving. Bureau of Labor Statistics Consumer Expenditure Survey data has historically shown that gasoline spending as a share of household income runs two to three times higher for families in the bottom income quintile compared to those at the top. A sustained stretch above $4.50 nationally would widen that gap. Anecdotal reports from fuel-industry analysts in late May 2026 suggest some motorists are already shortening planned trips, increasing carpooling, or delaying vacation departures in response to higher pump prices.
The ripple effects extend beyond the gas pump. Diesel prices, which the EIA also tracks weekly, influence the cost of shipping goods by truck. When diesel climbs alongside gasoline, consumers can end up paying more at the grocery store and the fuel station simultaneously.
Is any relief on the table?
In 2022, the Biden administration responded to record pump prices by releasing roughly 180 million barrels from the Strategic Petroleum Reserve over several months. Whether the current administration considers a similar move, or whether Congress revisits proposals for a temporary federal gas tax holiday, remains an open question as of late May 2026. Neither measure has been formally announced.
At the state level, California lawmakers have periodically debated gas-price relief measures, including rebate checks and investigations into refinery pricing. Governor Newsom signed a law in 2023 creating a watchdog agency to monitor refinery profits, but the agency’s authority to directly lower prices is limited.
What to watch through June 2026
Several factors will determine whether prices keep climbing or start to ease in the weeks ahead.
Inventory data is the most immediate signal. If the EIA’s weekly reports show gasoline stocks stabilizing or rebuilding, that would indicate refineries are catching up with demand, a necessary condition for prices to plateau. Continued drawdowns would point to more pain ahead.
Crude oil prices matter on a slightly longer timeline. Any shift in OPEC+ output policy or a slowdown in global economic growth could pull crude lower and eventually ease pressure at the pump, though changes in crude markets typically take two to four weeks to filter through to retail gasoline.
California refinery timelines deserve particular attention. The state’s thin supply margins mean even a one- or two-week delay at a major facility can add 20 to 30 cents per gallon quickly.
The EIA updates its national and regional price data every Monday. For drivers watching their budgets, those weekly releases are the most reliable, methodologically transparent gauge of where prices actually stand. The agency’s published methodology explains how it weights station-level data to reflect what consumers actually pay at the pump.
Right now, the picture is clear enough: American drivers have not faced fuel costs like these since the summer of 2022, and California is absorbing the worst of it. Whether that changes depends on refinery output, crude markets, and how quickly consumers adjust their driving habits. All three will play out in the weekly EIA data through June 2026.
