U.S. Regional Gasoline Prices as of May 28, 2025

In the previous week, gas prices have hovered between $3.12 and $3.16 per gallon nationally. As of May 28, the national cost of gas currently stands at $3.16, according to U.S. Energy Information Administration (EIA) data. However, prices year-over-year are down by 41.7 cents.

According to Gas Buddy's data compiled from more than 12 million individual price reports, the national average is up 3.1 cents from a month ago and is 43.0 cents per gallon lower than a year ago. The most common U.S. gas price was $2.99 per gallon, unchanged from last week.

“While the national average didn’t fall quite as far as anticipated for Memorial Day, it was still one of the most affordable since 2021 — and, when adjusted for inflation, among the cheapest in nearly a decade,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “As we move into the heart of summer, I believe we’re likely to see a relatively stable stretch for gas prices as refinery maintenance wraps up. Don’t expect the national average to rise above $3.30 per gallon, nor drop much below $3 for now.”

De Haan cited uncertainty around the hurricane season as a factor that could influence fuel prices in the weeks ahead. 

Here’s a look at prices by region according to EIA data, as of May 27:

• East Coast: $2.99

• Midwest: $3.01

• Gulf Coast: $2.72

• Rocky Mountain: $3.11

• West Coast: $4.25

Although the national average did not change much, the West Coast saw the greatest increase in the past week of about 6 cents, and the Rocky Mountain region saw the greatest decline of less than 1 cent.

In the previous three weeks, gas prices have hovered between $3.14 and $3.17 per gallon. As of May 20, the national cost of gas currently stands at $3.17, according to U.S. Energy Information Administration (EIA) data. However, prices year-over-year are down by 41 cents.

Meanwhile, GasBuddy shows a similar trend. Gas prices rose in most U.S. states over the past week, driven by surging oil prices tied to President Trump’s tariff reductions and new trade deals, which sparked economic optimism. According to Patrick De Haan of GasBuddy, while prices are still lower than last year, the gap is closing, though motorists can still expect one of the most affordable summers for travel in recent years.

U.S. Regional Gasoline Prices as of May 12, 2025

In the previous week, gas prices dipped slightly after a short uptick. The national cost of gas currently stands at $3.12, according to U.S. Energy Information Administration (EIA) data. Prices year-over-year are down by 48 cents.

Even though gas prices have fluctuated in recent weeks, the changes are hovering in the same range for most U.S. states. According to GasBuddy’s Head of Petroleum Analysis, Patrick De Haan, the price of gasoline has resumed its decline as refineries wrap up seasonal maintenance and prepare to boost output.

However, some increases were seen on the West Coast last week due to a fire at the Valero refinery in Benicia, California. On the other hand, trade war de-escalation between the U.S. and China could push gas prices up in the coming weeks.

“As we approach Memorial Day, gas prices may see some minor fluctuations, but for now, I don’t expect any significant changes to the national average, with prices staying near their lowest seasonal level since 2021,” De Haan said.

U.S. Regional Gasoline Prices as of May 5, 2025

Gas prices have risen ever so slightly in the past week, the first upward tick in almost a month. The national cost of gas currently stands at $3.14, according to U.S. Energy Information Administration (EIA) data. Prices year-over-year are down by 49 cents.

Although last week offered another mixed bag of changes for fleets and consumers alike, not much movement was seen in the national average. This slight change could be due to some regions seeing increases while others saw modest declines.

“We continued to see price cycling in states prone to such movements, including much of the Great Lakes region, as well as in Maryland, Florida, and parts of Texas,” De Haan, said.

According to De Haan, there may be some promising short-term news from OPEC+, which “has agreed to increase oil production starting in June”.

“The most notable development is OPEC+’s decision to raise production next month, as oil prices hover near their lowest levels since the pandemic,” De Haan said.

Certain gasoline inventories have been tightening because of refinery maintenance, which has impacted the amount gas prices have recently fallen. However, refinery output is expected to rise. Considering maintenance wraps up and an increase in gasoline supply, there is the potential for the national average to fall below $3 per gallon.

Here’s a look at prices by region according to EIA data, as of May 5:

• East Coast: $2.99

• Midwest: $3.02

• Gulf Coast: $2.72

• Rocky Mountain: $3.11

• West Coast: $4.15

Although the national average did not change much, there have been minor fluctuations from region to region. The West Coast saw the greatest decline in the past week of about four cents, and the Midwest and Gulf Coast regions saw the greatest increase of about four cents.

Here’s a look at the top 10 cheapest states to buy gas, according to AAA data:

In recent months, Mississippi has held the top spot for the lowest price for a gallon of gas, as no other states have dipped low enough to become a threat to first place. Missouri makes its return to the list, bumping New Mexico to spot number 12. Texas, a previous contender for the top spot, has fallen to seventh place.

Currently, 24 states have a $2.99 or lower average for a gallon of gas.
