U.S Regional Gasoline Prices as of September 29, 2025

The national average for gas prices decreased 5.8 cents over the last week.  

The current national cost of gas stands at $3.09 per gallon, according to GasBuddy data. In addition, data compiled from more than 12 million individual price reports covering over 150,000 gas stations nationwide shows that the national average decreased 1.1 cents from a month ago and is down 9.0 cents from a year ago.

Patrick De Haan, head of petroleum analysis at GasBuddy, commented on the notable drop in prices.

“Gas prices have seen a notable weekly drop in most states as seasonal factors ramp up their impact — namely the switch to cheaper winter gasoline and falling gasoline demand,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Price cycling markets led the way with significant declines in Ohio, Florida, and Michigan, while Indiana experienced a price cycle that resulted in the largest weekly increase of any state last week. For now, seasonal factors will remain the primary driver of relief at the pump, though we continue to monitor the tropics for any potential disruptions.”

• East Coast: $3.12

• Midwest: $2.93

• Gulf Coast: $2.67

The national average for gas prices increased by 2.2 cents over the last week. 

The current national cost of gas stands at $3.14 per gallon, according to GasBuddy data. In addition, data compiled from more than 12 million individual price reports covering over 150,000 gas stations nationwide shows that the national average remains unchanged from a month ago and is down 1.8 cents from a year ago.

Patrick De Haan, head of petroleum analysis at GasBuddy, says the nation is still on track to see the national average fall below $3 per gallon during the Fall. 

“The national average saw a slight increase last week, primarily driven by states that experienced price cycling just ahead of the switch back to winter gasoline,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Florida, Ohio, Michigan, and Maryland— all states known for routine price cycling — saw double-digit jumps to average gas prices. Now that much of the nation has begun the transition to cheaper winter gasoline, and with driving demand seasonally tapering off as temperatures dip, gas prices face additional downward pressure. We’re still on track to potentially see the national average fall below $3 per gallon for the first time in years this autumn.”

Here’s a look at prices by region according to EIA data, as of September 22: 

• East Coast: $3.03

• Midwest: $3.00

• Gulf Coast: $2.72

• Rocky Mountain: $3.18

• West Coast: $4.27

The West and Gulf Coasts are the only regions that saw a slight decrease in fuel prices. 

Oklahoma retakes its position as the state with the cheapest gas.

U.S Regional Gasoline Prices as of September 15, 2025

The national average for gas prices decreased by 3.6 cents over the last week. 

The current national cost of gas stands at $3.12 per gallon, according to GasBuddy data. In addition, data compiled from more than 12 million individual price reports covering over 150,000 gas stations nationwide shows that the national average is down 1.8 cents from a month ago and down 2.8 cents from a year ago.

Patrick De Haan, head of petroleum analysis at GasBuddy, expects prices to fall as the colder months approach. 

“While gas prices fell in more states than they rose last week, the West Coast continues to face challenges, with Oregon and Washington seeing some of the largest increases due to regional infrastructure issues,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The good news is that the transition to cheaper winter gasoline begins tomorrow across most of the nation, and with improvements underway in the West Coast market, I expect that average gas prices will continue to decline in the weeks ahead in most states — assuming hurricane season remains quiet.”

Here’s a look at prices by region according to EIA data, as of September 15: 

• East Coast: $3.01

• Midwest: $2.98

• Gulf Coast: $2.77

U.S Regional Gasoline Prices as of September 8, 2025

The national average for gas prices has increased slightly by 0.3 cents. 

The current national cost of gas stands at $3.16 per gallon, according to GasBuddy data. In addition, data compiled from more than 12 million individual price reports covering over 150,000 gas stations nationwide shows that the national average is up 3.1 cents from a month ago and down 6.1 cents from a year ago.

Patrick De Haan, head of petroleum analysis at GasBuddy, commented on the increase as well as relief in the Midwest due to BP’s refinery. 

“Most of the nation’s 50 states saw gas prices rise over the last week, while some Great Lakes states saw significant relief thanks to the restart of BP’s Whiting, Indiana, refinery after severe weather caused a temporary outage,”

“GasBuddy counts 17 states with average prices below $3 per gallon — fewer than we’ve seen in recent months. Ohio, Michigan, Indiana, Kentucky, and Illinois led the declines, while just a few additional states saw price drops. Meanwhile, the West Coast is expected to see continued increases in California, Oregon, Washington, Arizona, and Nevada due to seasonal refinery maintenance and the shutdown of a refinery in Southern California, which will keep supply tight. However, with the transition back to winter gasoline just a week away for most areas, those increases may be short-lived, with potential relief arriving toward the end of the month. Additionally, OPEC+ announced an increase in oil production starting in October, which could help keep oil prices lower for longer.”

Here’s a look at prices by region according to EIA data, as of September 8:

U.S Regional Gasoline Prices as of September 2, 2025

National gas prices reached record lows over the Labor Day holiday weekend, though they’ve been edging up this week.

The current national cost of gas stands at $3.15 per gallon, according to GasBuddy data. In addition, data compiled from more than 12 million individual price reports covering over 150,000 gas stations nationwide shows that the national average is up 1.6 cents from a month ago and down 13.1 cents from a year ago.

“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.”

Here’s a look at prices by region according to EIA data, as of September 2: 

• East Coast: $3.01

• Midwest: $3.08

• Gulf Coast: $2.77
