The Most Expensive (And Cheapest) Gas In America Right Now

The national average price for a gallon of regular gas has ticked up in the last month and has crossed the $4.00 mark once again. According to the latest data gathered from AAA the price now sits at $4.072, up from $3.782 a month ago.

It was $3.1558 one year ago, and prices are up a few cents since last week, with the ongoing conflict in the Middle East sending crude oil prices up again. However, the average fails to reflect the significant price variation across states.  

California is the state with the most expensive gas in the nation, with a gallon of gas costing $5,581, up $0.12 from mid-July. That beats out Hawaii in second which sits at $5.434. Washington remains the state with the third-highest average price at $4.162, and prices in both states are up from a month ago.

At the opposite end of the spectrum, drivers across the central and southern US are paying the least for regular gas. Louisiana now has the cheapest gas on average at $3.574 a gallon. 

Indiana is the state with the second-cheapest gas at $3.590 a gallon, with prices rising by more than $0.20 in "The Sooner State." Mississippi is third at  $3.604, up $0.16 from last month. 

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 $4.584 396 and $4.966 4.774 for those fuel types, up about $0.11 from a month ago, and about $1 more than a year ago. 

Diesel customers are paying a whopping $5.404 a gallon on average, up $1.69 from a year ago, with prices continuing to rise. 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.
