Gas prices remain above the $4.00 mark in the US, and continue to rise.
The national average price for a gallon of regular gas continues to climb, remaining above the $4.00 mark. According to the latest data gathered from AAA, the price now sits at $4.151, up from $4.022 a month ago.
The average was around $3.782 in mid-July and $3.200 one year ago. The ongoing conflict in the Middle East continues to affect gas prices. However, the average fails to reflect the significant price variation across states.
California remains the state with the most expensive gas in the nation, with a gallon of regular increasing by nearly $0.30 to $5.866. That beats second-place Washington, which saw prices rise from $5.162 in August to $5.510 today.
Hawaii has the third-highest price for a gallon of gas at $5.392, up from $5.162 last month. Alaska and Oregon are the only two other states with gas averaging over $5.00 a gallon.
At the opposite end of the spectrum, drivers in several states are paying considerably less for regular gas. Indiana now has the cheapest gas on average in the nation at $3.423. Texas is second with prices at $3.673. Oklahoma is third at $3.706.
The increase in the average price for a gallon of regular gas over the last month coincides with a rise in mid-grade and premium prices, too. US consumers are now paying $4.634 and $4.966 for those fuel types, up about a nickel from a month ago, and about $1 more than a year ago.
Diesel customers are somehow paying even more than before. The average price jumped $0.60 from a month ago, with the price rising $0.30 in the last week to $5.901. That is $2.20 more than a year ago.
These trends offer a stark picture for consumers: Gas prices remain high and continue to rise for many, with many new car buyers turning to hybrids.
Here’s a closer look at how average gas prices break down by state (as of September 8, 2026):
