INDIANA – Average gasoline prices across Indiana fell by 7.8 cents per gallon over the past week, bringing the state average down to $3.50 per gallon, according to GasBuddy’s survey of 3,271 Hoosier stations.

While local motorists are seeing slight relief at the pump—with Indiana prices sitting 1.7 cents per gallon lower than a month ago—rates remain 38.0 cents higher than this time last year. Across the state, prices varied widely: yesterday’s lowest reported price stood at $2.99 per gallon, while the highest reached $4.09 per gallon, marking a $1.10 per gallon spread.

Divergent Trends: Indiana Relief vs. National Increases
Unlike Indiana’s weekly dip, the overall U.S. average gasoline price rose 2.9 cents per gallon over the past week to $4.05 per gallon. The national average is down 5.0 cents per gallon from a month ago but stands 92.6 cents higher than a year ago, based on GasBuddy data compiled from more than 11 million weekly reports across 150,000 nationwide stations.
Meanwhile, diesel fuel experienced a sharp jump nationwide, increasing 16.6 cents in the last week to reach $5.584 per gallon.

Refinery Constraints Keep Upward Pressure on Prices
Fewer than 10 states saw gasoline price declines over the past week, making Indiana’s drop a notable exception to a broader national surge. Petroleum analysts point to international supply bottlenecks and refinery disruptions as the primary drivers keeping fuel costs elevated.

“Average gasoline prices moved higher in the majority of states over the last week, with fewer than 10 states seeing declines, while diesel surged nearly 17 cents per gallon nationally, leaving it less than 25 cents away from an all-time record high,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
De Haan noted that gasoline prices nationally are currently at their highest level ever recorded for this late in the calendar year.
“Americans could for the first time ever see a national average price of gasoline above $4 per gallon on Labor Day — eclipsing the previous record of $3.83 per gallon set in 2012,” De Haan explained. “While some oil shipments are apparently getting through the Strait of Hormuz, the dominant force propping up both gasoline and diesel prices is increasingly the growing loss of Russian refinery capacity, as continued Ukrainian attacks knock more facilities offline and constrain the global supply of refined fuels. Until that refining supply picture improves, both gasoline and diesel prices face continued upward pressure.”
