American oil fields pumped a record 13.2 million barrels per day in 2024, more than Saudi Arabia or Russia, according to the U.S. Energy Information Administration. Monthly output peaked at 13.4 million barrels per day in August of that year, the highest single-month figure ever recorded. By any measure, the United States is the world’s dominant oil producer.
Yet as of spring 2026, the national average price for a gallon of regular gasoline has remained stubbornly above $3.00, according to AAA’s fuel gauge report. For drivers filling up in California, Pennsylvania, or Illinois, the number is considerably higher. The disconnect between record production and persistent pump prices is not a mystery, but the explanation involves layers that raw output numbers alone cannot capture.
Record production, constrained refining
The 2024 output of 13.2 million barrels per day represented a gain of roughly 300,000 barrels per day over the prior record set in 2023. But crude oil is not gasoline. Every barrel has to pass through a refinery, and that is where the supply chain tightens.
The United States lost meaningful refining capacity during the pandemic. Several facilities shut down permanently, including the Philadelphia Energy Solutions complex, which had been the largest refinery on the East Coast before a 2019 explosion and fire accelerated its closure. New investments have partially offset those losses. ExxonMobil’s expansion at its Beaumont, Texas, facility added capacity, and based on Form EIA-820 annual refinery survey data, operable atmospheric distillation capacity rose by roughly 324,000 barrels per day in 2023. But the net recovery has not fully replaced what was lost, and the EIA’s short-term gasoline outlook has noted that tight capacity continues to support elevated refining margins.
When capacity is tight, refiners can charge more for every gallon they produce because there is less competition for throughput. The “crack spread,” a rough measure of the profit margin between crude oil input costs and refined product output prices, has remained elevated compared to pre-pandemic norms. Seasonal dynamics compound the problem: the mandated switch to summer-blend gasoline each spring raises production costs, and hurricane season along the Gulf Coast can knock facilities offline for weeks. Those margin spikes land directly on the pump price, even when crude oil itself is getting cheaper.
A tax floor that never drops
The federal gasoline excise tax sits at 18.4 cents per gallon. It has not changed since October 1993. The federal diesel tax, at 24.4 cents per gallon, has been frozen just as long. Both figures are documented by the Federal Highway Administration.
State taxes and fees stack on top, and the variation is enormous. As of early 2025, combined state-level charges on gasoline ranged from under 15 cents per gallon in Alaska to well over 60 cents per gallon in California and Pennsylvania. Some states index their fuel taxes to inflation or wholesale fuel prices, meaning rates adjust automatically without a legislative vote. Others set flat rates that move only when lawmakers act. California layers additional costs through programs like the Low Carbon Fuel Standard and requires specialized CARB gasoline blends, which limit the pool of suppliers and push prices well above the national average.
Together, federal and state taxes typically account for roughly 13 to 15 percent of the retail price of a gallon of gasoline, based on the EIA’s price component breakdown. Because taxes are largely fixed per gallon rather than calculated as a percentage of price, they act as a floor: even if crude oil prices collapse, the tax layer prevents pump prices from falling below a certain threshold.
The export factor
One dynamic that often gets overlooked: the United States exports a large share of the crude oil it produces. In 2024, the country shipped roughly 4 million barrels per day of crude to foreign buyers, according to EIA export data. That oil enters the global market, where prices are set by international benchmarks like West Texas Intermediate and Brent. Producing more oil at home puts some downward pressure on those benchmarks, but it does not create a walled-off, cheaper pool of crude reserved for American refineries.
The same logic applies downstream. U.S. refineries are among the world’s largest exporters of gasoline, diesel, and jet fuel, shipping millions of barrels per day to Latin America, Europe, and other markets. That export demand competes with domestic consumption for refinery output, which helps keep refining margins elevated even when crude supply is plentiful at home.
OPEC+ and capital discipline add pressure from the other direction
Record U.S. output does not exist in a vacuum. The OPEC+ alliance, led by Saudi Arabia and Russia, has maintained production cuts through much of 2024 and into 2025 in an effort to support global crude prices. Those cuts remove millions of barrels per day from the world market, propping up the benchmark prices that U.S. refiners pay for their feedstock, regardless of how much oil comes out of West Texas or North Dakota.
Meanwhile, the U.S. producers responsible for record output have not been chasing volume for its own sake. Since the shale bust of 2015-2016, publicly traded exploration and production companies have prioritized returning cash to shareholders through dividends and buybacks over aggressive drilling. This capital discipline means production growth, while steady, has been more restrained than geology alone would allow. The result is a market where U.S. output sets records but does not flood the system with enough surplus to dramatically undercut global prices.
What the price breakdown actually shows
The EIA divides every gallon of retail gasoline into four cost components: crude oil, refining costs and profits, distribution and marketing, and taxes. Crude oil is consistently the largest slice, typically accounting for more than half the pump price. But the other three components are sticky. Refining margins do not fall in lockstep with crude. Distribution costs reflect trucking, pipeline tariffs, and terminal fees that change slowly. And taxes, as noted, barely move at all.
This layered structure is why a 10 percent drop in crude oil prices never produces a 10 percent drop at the pump. The non-crude costs absorb part of the decline, and in some cases, rising refining margins or new state fees can offset a crude price drop entirely.
Abundance and affordability are not the same thing
For drivers watching the price board at their local station, the math is frustrating but consistent. The United States pumps more oil than any nation on earth, yet gasoline prices remain shaped by refinery constraints, global commodity pricing, OPEC+ strategy, producer discipline, and a tax structure that has barely been updated in three decades. Record crude production does reduce one input cost, and it strengthens the country’s energy trade balance. But it cannot, on its own, override the refining bottleneck, the global market’s pull on supply, or the fixed tax layer baked into every gallon.
Until refining capacity grows enough to create sustained slack, or fuel tax policy gets a meaningful overhaul, the gap between what America produces underground and what Americans pay at the pump is likely to persist. Pumping the most oil in the world, it turns out, does not guarantee the cheapest gasoline.
