American drivers woke up to fresh pain at the pump this week. The national average for regular gasoline climbed to $4.536 a gallon, the highest reading since July 2022, while California shoppers stared down sticker shock at $6.16. The gap between the priciest and cheapest states has stretched past $2, exposing a deep regional split that is reshaping household budgets just before summer travel.
What Sparked the Latest Pump Price Jump
The surge is being driven by a tangle of global conflict, refinery breakdowns, and the seasonal switch to summer fuel. The national average hit $4.536 as of Wednesday, a rise of about 5 cents from Tuesday’s average of $4.483, AAA said.
American drivers have been seeing prices at the pump increasing since the U.S. and Israel launched joint strikes on Iran on February 28. Prices had been steadily falling prior to the war, with the nationwide average dipping to $2.98 on February 26. That works out to a brutal climb of roughly 50 percent in just over two months.
Crude oil sits at the heart of the story. The Energy Information Administration estimated that in 2026 oil prices represented about 51 percent of the price of gas per gallon. The Iran war has effectively put a chokehold on the Strait of Hormuz, throttling traffic through the narrow channel, which normally sees the passage of ships carrying one fifth of the world’s oil.
There is one ray of hope. US gasoline futures eased to $3.63 per gallon from a near four-year high of $3.74 reached on May 4, after Washington downplayed the risk of a renewed full-scale conflict with Iran. Gasoline fell to $3.47 per gallon on May 6, down 4.26 percent from the previous day.

Where Drivers Pay the Most and the Least
The state-by-state breakdown reads like two different countries. In California, where drivers paid the highest price for gas, the statewide average reached $6.160 on Wednesday. In Oklahoma, where they paid the lowest, the statewide average was $3.962 per gallon.
| Most Expensive States | Average Price |
|---|---|
| California | $6.16 |
| Hawaii | $5.64 |
| Washington | $5.51 |
| Oregon | Top 5 |
| Nevada | Top 5 |
California remains the state with the highest statewide average gas price in the country. This is followed by Hawaii at $5.64 per gallon. Next is Washington state at $5.51 per gallon. Oregon and Nevada are the remaining two states in the top five.
On the cheaper side of the map, the Plains states are still the place to be. Oklahoma continues to have the lowest gas prices in the country at $3.57 per gallon. This is followed by Kansas at $3.634 per gallon. Georgia makes its debut on the list of five most affordable states for gas prices with a statewide average of $3.65 per gallon. Arkansas is next at $3.684 per gallon, followed by Mississippi at $3.717 per gallon.
The Great Lakes Shock and a Possible Break
The Midwest just lived through one of the wildest price spikes of the year. In Michigan, the average price for regular unleaded hit $4.86 a gallon on Monday after soaring more than 85 cents in a week. Indiana, Ohio, Illinois and Wisconsin saw similar spikes, pushing Michigan drivers to pay an average of $73 for a 15-gallon fill-up.
De Haan noted that the Great Lakes saw some of the fastest and steepest increases in the country, with wholesale gasoline, diesel and even jet fuel surging as multiple refineries struggled to stay online.
“If refinery operations continue to normalize, Great Lakes drivers should see noticeable price drops by mid-May.”
That outlook comes from GasBuddy’s head of petroleum analysis, Patrick De Haan. He said in a post on X that average gasoline prices in the region could drop 20 to 40 cents per gallon, with diesel falling 25 to 60 cents, barring any new global disruptions.
How Households and the Economy Feel the Squeeze
Higher fuel costs hit working families first. A 15-gallon fill-up that cost $44 in late February now runs about $68 at today’s national average. Multiply that by two cars and four weekly trips, and the math turns ugly fast.
The political mood is turning sour, too. According to a recent survey by Quinnipiac University, 65 percent of voters say they blame Trump either “a lot” or “somewhat” for the increase in gas prices, compared to 45 percent who said they blame him little or not at all. The findings suggest growing public frustration as everyday expenses climb.
Industry chiefs are not promising relief either. Chevron CEO Mike Wirth warned that predicting the next move is nearly impossible right now. “Even in normal times, markets can surprise you. This is not a normal time. The dynamics that are affecting supply are quite unusual,” he told CBS, adding that higher prices would likely stick around.
Smart ways drivers can soften the blow right now:
- Use apps like GasBuddy or AAA TripTik to compare local stations before filling up.
- Pay with a fuel rewards or cashback card to claw back 3 to 5 percent per gallon.
- Combine errands into one trip and keep tires properly inflated to stretch each tank.
- Avoid premium grades unless your owner’s manual requires them.
- Consider midweek fill-ups, since prices often climb on Thursdays and Fridays.
What Comes Next at the Pump
The next two weeks will decide a lot. If Middle East tensions cool further and Midwest refineries fully restart, the national average could drift back toward $4.20 by Memorial Day weekend. If the Strait of Hormuz situation flares again, $5 a gallon nationally is no longer a far-fetched headline.
Gasoline production decreased last week, averaging 9.6 million barrels per day, a sign supply is still tight. Energy Information Administration data showed gasoline demand edged higher to 9.10 million barrels per day, while inventories fell and production declined slightly. When supply slips and demand rises into Memorial Day, the pump rarely cooperates with the consumer.
For now, the United States is split into two driving worlds. One pays $3.96 in Oklahoma and grumbles. The other pays $6.16 in California and rearranges the family budget. Behind every gallon are real choices being made at kitchen tables across the country: skip a vacation, cut a dinner out, postpone a repair. The numbers on the sign outside your local station are not just economics. They are a measure of how far global politics now reaches into everyday American life.
