“With the unofficial end of summer now behind us, we saw the lowest national average price of gasoline on Labor Day since 2020, with prices lower than a year ago in all but three states,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “This caps off the most affordable summer at the pump since 2021, with motorists spending $11.3 billion less on gasoline compared to last year. While summer may be in the rearview mirror, low gas prices aren’t going anywhere anytime soon. In fact, so long as we avoid major hurricanes or other disruptions, we’re on solid footing to see the national average dip to $2.99 per gallon this fall.”
