August to September in one series
Both monthly figures come from the same series, the average price of regular gasoline in dollars per gallon. That makes them directly comparable. September's 4.482 is higher than August's 4.2, so the price rose.

Motor fuel price inflation, a 12-month change, was 34.2% in September 2026. This is a percentage change in a price index, not an average pump price. It should not be read as the change in the 4.482 figure.

What the data does not tell us
The data covers only two months of the gasoline average, so it cannot show a longer trend. It also does not explain why the price rose. It gives no information on regional differences or on how much people drove.

AI analyst view
Little change expected low confidence next two monthly releases
Estimate range: 4.20–4.60 USD/gal
Why
- September's monthly jump of 0.28 dollars per gallon shows strong recent momentum, which tends not to reverse within a single month. F1 F3
- US gasoline prices usually soften in the fall as summer driving fades and cheaper winter-blend fuel enters the market. That seasonal pull works against further gains. F1 F2
- Motor fuel price inflation at 34.2% over 12 months shows fuel prices already sit well above a year earlier. Prices that have run up that far often stall rather than keep climbing at the same pace. C129
What would change this view
- If the next monthly change is again 0.28 dollars per gallon or more, pointing to a continued rise
- If the average falls below the August level of 4.2 dollars per gallon, pointing to a clear decline
- If diesel moves well above 5.43 dollars per gallon, signaling broader fuel price pressure
This is the AI’s own interpretation of the official figures above, not an official forecast. It may turn out wrong.
Scenarios to watch
- Scenario, not a forecast If the monthly increase seen in September repeats in October, the average gasoline price would move further above 4.482 dollars per gallon.
- Scenario, not a forecast If the usual seasonal easing in fuel demand after summer takes hold, the average could settle back toward the August level of 4.2 dollars per gallon.
What to check next
- The October 2026 average price of regular gasoline and its change from September
- The next reading of motor fuel price inflation, a 12-month change, against the September figure of 34.2%
- The September 2026 diesel average of 5.43 dollars per gallon in the next release
