AAA's daily tracker puts the U.S. regular-gas average at $4.528 on Friday, May 15, 2026. That is only a small daily dip, but it changes the tone from an accelerating pump-price tape to a market trying to stabilize.

The practical read is simple: drivers are not seeing real relief yet. They are seeing the first sign that the national average has stopped climbing while crude oil remains expensive. Reuters reported through Investing.com that Brent was near $106.32 and WTI near $101.71 early May 15 as ship-attack and Hormuz transit concerns kept crude supported.
Gas Prices Today: The Real Numbers
- Regular gasoline: $4.528 nationally.
- Mid-grade gasoline: $5.016 nationally.
- Premium gasoline: $5.391 nationally.
- Diesel: $5.662 nationally.
- E85: $3.663 nationally.
AAA's table showed regular gasoline down from $4.534 yesterday and $4.546 a week ago, but still well above the month-ago average of $4.108 and the year-ago average of $3.193. That is the household story: week-over-week pressure is easing, but the pump bill is still far above normal.
The U.S. Energy Information Administration is the slower government check. EIA's petroleum data page lists gasoline and diesel updates by region. AAA is better for the daily number; EIA is better for weekly confirmation.
State Gas Prices: Expensive West, Cheaper Gulf States
AAA's state map still shows a brutal regional spread. California was around $6.142 for regular gasoline, Washington around $5.775, and Hawaii around $5.648. At the low end, Texas was around $3.996, Mississippi around $4.000, and Louisiana around $4.006.
That gap matters because the national average can hide very different household pressure. A family in California is dealing with a price level more than $1.60 above the national figure, while drivers in Texas are still just under $4.00.
Why Gas Is Not Falling Faster
Retail gasoline lags crude. Even when oil futures soften, stations are working through wholesale prices, local supply, summer-grade fuel requirements, and inventory costs already in the system. That lag is why a small decline in the AAA average can coexist with crude staying above $100.
The latest oil story also argues against assuming quick relief. Reuters said the main driver remained tight supply, with some ships passing through the Strait of Hormuz but traffic still far below pre-war norms. As long as crude holds above $100, gasoline has less room to fall.
What Drivers Should Watch Next
The clean dashboard is AAA regular gasoline, AAA diesel, Brent crude, WTI crude, and EIA inventory updates. If crude slips back below $100 and AAA's daily number keeps drifting lower for several days, the pump-price peak may be in for now. If shipping risk worsens and crude pushes higher again, this small decline will not mean much.
Diesel deserves special attention. At $5.662, it is still the number that bleeds into freight, grocery delivery, construction, and farm costs. Regular gasoline gets the headlines, but diesel is the fuel cost that moves through the supply chain.
Bottom Line
Gas prices are slightly lower today, not cheap. AAA's $4.528 national regular average is down from yesterday and a week ago, but it is still far above the month-ago and year-ago levels. The better read is that pump prices are stabilizing while the market waits to see whether crude oil finally breaks lower.
For now, the oil risk premium is still alive. Drivers need several more days of lower AAA readings before this looks like real relief rather than a pause.
