U.S Regional Gasoline Prices as of May 4, 2026


According to GasBuddy data compiled from more than 12 million individual price reports covering over 150,000 gas stations across the country, the national average for fuel has risen 38.2 cents over the last week and stands at $4.42 per gallon.

This is up 38.2 cents per gallon from a month ago and 1.31 cents per gallon higher than a year ago.

“Gasoline prices rose in every state over the last week, with some of the most significant and fastest increases concentrated in the Great Lakes, where states like Michigan, Indiana, Ohio, and Illinois saw sharp spikes, while Wisconsin experienced more modest gains,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “At the same time, diesel prices surged to new records in parts of the region, with some areas touching the $6-per-gallon mark. While refinery outages were a key driver behind those outsized increases, early signs of improvement could help ease some of the most extreme price pressures in the Great Lakes in the days ahead. Beyond the region, markets are also digesting a wave of new developments—including OPEC+ raising production for June and President Trump outlining a plan to free stranded ships—which could help restore some supply. However, with so many moving pieces, the outlook remains highly fluid, and while some localized relief may emerge, broader price volatility is likely to persist in the near term.”

Here’s a look at prices by region according to EIA ata, as of May 4:

  • East Coast: $4.25
  • Midwest: $4.40
  • Gulf Coast: $3.90
  • Rocky Mountain: $4.36
  • West Coast: $5.83
