The National Average Is One Number. Your Driveway Is Another.

Published on 2026-09-21

AAA has the national average holding at $4.09 a gallon as high oil prices keep fuel costs elevated, and reports on how much EV drivers save now come broken out state by state. Both facts point the same way: the headline number is a starting point, not your bill.

Gasoline: a record August, and a lag that hasn't cleared

August set a record for U.S. gas prices, and Massachusetts drivers paid more than the national figure — a reminder that a single average can hide a wide local range. With the national average holding at $4.09, the story this week isn't movement, it's stickiness: crude has stayed firm, and because pump prices trail the oil market by roughly one to two weeks, part of what you're paying now was set before you filled up.

That lag cuts both ways. If crude eases, relief shows up slowly and unevenly, filtered through state taxes, refinery logistics and local retail margins. If it firms, the pressure builds the same quiet way. Neither outcome is a forecast — it's just how the chain works, and it's why two stations a few miles apart can post very different numbers on the same morning.

Households have already voted on this. Rising prices pushed many U.S. buyers toward hybrids rather than straight to electric — a hedge that trims the gallon count without asking anyone to rebuild their refueling habits. It's a practical response to a market where the pump price is elevated but not predictable.

Charging: the cheapest mile depends on where you plug in

The recurring question — is it cheaper to run on gas or electricity? — has a boring but honest answer in the U.S.: it depends on your utility, your rate plan and whether you charge at home or on a public DC fast network. Home charging on an off-peak window is the low end of the range. Public fast charging, priced per kilowatt-hour or per minute and often with idle fees, sits at the high end, and that's where the gap with gasoline narrows.

That's exactly why EV savings estimates are now published state by state instead of as one national figure. Electricity prices vary by region far more than gasoline taxes do, and time-of-use plans mean the same charger in the same garage can cost noticeably different amounts at 6 p.m. and at 1 a.m. Shifting a weekly charge into the cheaper window is the EV equivalent of driving past the expensive corner station.

Australia's EV uptake has been driven largely by cheap home charging and rooftop solar — a useful contrast. In the U.S., where commutes are longer and public fast charging carries more of the load, the electricity side of the ledger is less automatic and more worth managing.

One move this week

Whatever you drive, the money is in the spread, not the average. Before your next fill-up, compare the cheapest and most expensive stations on your normal route rather than defaulting to the one nearest the highway exit — on a multi-gallon tank, that difference is the largest single saving available to you this week. Refil shows both the cheapest gas station and the cheapest EV charger near you on one map, which is the simplest way to blunt an elevated average.

EV drivers: check whether your utility has a defined off-peak window, and move one weekly charge into it. If you're relying on public fast charging by habit rather than necessity, price a home or workplace session against it before you plug in again.
