Here are this week’s gasoline price highlights from each region of the U.S.:

According to AAA, the current national gasoline price average is $3.121. This is 0.3 cents lower than EIA’s current estimate and 5 cents lower than this time last year.

In a recent press release, AAA said, "'Tis the season for lower gas prices as demand drops and gas stations make the switch to winter-blend gasoline, which is cheaper to produce. Crude oil supply remains robust as OPEC+, a group of oil-producing countries, is likely to announce in the coming days another production increase in November. That surplus, coupled with weaker demand, is keeping pump prices down, even as some U.S. refineries are expected to go offline this month for seasonal maintenance.”
