The national average for a gallon of regular gasoline came in at $4.071 last week, according to the U.S. Energy Information Administration’s Monday survey of retail stations across the country. That’s a few cents cheaper than the week before, but it sits 89 cents higher than drivers paid at the same point last year. For a household that fills up once a week, the small weekly dip barely registers next to the much larger year-over-year increase already showing up in the family budget.
A Fourth Straight Weekly Reading Above $4 a Gallon
EIA’s Gasoline and Diesel Fuel Update, released September 1 for the week ending August 31, put the U.S. average at $4.071 a gallon, down 1.4 cents from the $4.085 recorded seven days earlier. The survey samples roughly 900 retail outlets around 8 a.m. each Monday and reports self-service prices with all taxes included, or full-service where that’s the only option available in a given area. It’s the government’s own real-world benchmark for what drivers are actually paying at the pump, updated every single week without exception, rather than a forecast built from futures markets or refinery projections that may or may not show up at the register.

89 Cents More Than Last August, or $13.41 Extra Per Fill-Up
The number that matters more for a household budget is the year-over-year comparison. EIA’s weekly survey shows the current average running 89.4 cents, or 28.1 percent, above the same week in 2025. On a 15-gallon fill-up, that gap works out to $13.41 more than a driver paid a year ago for the identical trip to the same pump. Multiply that across roughly four fill-ups a month and the increase alone approaches $54 — money that doesn’t show up as one dramatic spike but accumulates quietly, receipt by receipt, in a category most households don’t line-item until the credit card statement arrives.
California and the West Coast Are Paying the Most, by a Wide Margin
Prices vary sharply by region, and the gap has only widened over the past year. The West Coast averaged $5.206 a gallon for the week, with California alone reaching $5.520 — up 7 cents from the week before even as the national number fell. Los Angeles hit $5.532 and San Francisco climbed to $5.552, while Seattle and Washington state both topped $5.25. On the other end of the country, the Gulf Coast averaged just $3.618, with Texas and Houston both running below $3.60. That’s a spread of more than $1.60 a gallon between the cheapest and most expensive regions in the same week, driven by differences in state fuel taxes, local blend requirements and how close a given market sits to refining capacity. The Midwest landed almost exactly in the middle at $3.847, a reminder that the $4.071 national number is itself an average of very different regional realities rather than a price most drivers are actually paying at any single pump.
Why the Weekly Dip and the Yearly Jump Tell Different Stories
The small weekly decline and the large annual increase aren’t in conflict with each other — they measure different forces. EIA’s own survey methodology notes that week-to-week movement reflects short-term shifts in crude oil costs, refinery output and regional supply disruptions, while the year-over-year comparison captures the slower, cumulative trend that has kept pump prices elevated through most of 2026. Some states saw the weekly swings do most of the work: Colorado’s average fell 25.2 cents in a single week and Ohio’s dropped 18.4 cents, both far larger moves than the national 1.4-cent dip. A driver who only tracks the weekly headline could easily miss that the underlying cost of driving has climbed substantially since last summer, even during weeks when the number ticks down.
The number itself comes from real purchases at the pump, not a model. EIA draws its weekly sample from a frame of roughly 130,000 active retail gasoline outlets nationwide, split between big-box stations — warehouse clubs and large discount retailers that typically sell at a deep volume discount — and every other conventional station, then collects prices by telephone, email, text, fax or the internet each Monday morning. Outlets that can’t be reached are handled through imputation, a statistical fill-in method, but EIA withholds an estimate entirely if imputed prices account for more than half of the weighted sales volume behind it. The finished number is released around 10 a.m. Eastern each Tuesday, or Wednesday during a government holiday week, which is part of why a figure like $4.071 carries real statistical weight rather than functioning as a rough guess.
Two Years of Compounding Increases at the Pump
Zoom out further and the trend looks steeper still. The same EIA data shows the current $4.071 average sitting 78.2 cents above the price two years ago — meaning pump prices have climbed in back-to-back years rather than spiking once and settling back down. For a household that still budgets gas costs against what it paid two summers ago, the compounding effect is larger than either single year-over-year comparison suggests on its own, and it means the relief many drivers keep expecting hasn’t materialized in the national average. On the same 15-gallon fill-up used earlier, that two-year gap adds up to $11.73 more per trip to the pump than in 2024, on top of whatever a household was already paying then — a second layer of cost stacked on the 89-cent year-over-year jump, not a separate, smaller problem.
What EIA’s Next Release Could Show
EIA’s next weekly update is scheduled for September 9 and will cover the first full week of September. Gasoline demand typically eases once the unofficial end of summer driving season passes over Labor Day, which can nudge weekly averages lower even while the year-over-year gap persists into the fall. For household budgeting purposes, the 89-cent increase already recorded this week is the figure that matters most — it reflects money already spent at the pump this year, not a temporary spike that’s likely to reverse itself before the next tank of gas.
