Gas prices are up significantly across the US, with the national average for a gallon of regular now at $4.06.
The national average price for a gallon of regular gas has crossed the $4 mark, $1 more than just one month ago. The price now sits at $4.06 a gallon, according to the latest data gathered from AAA. That’s up from $2.98 just a month ago, with the conflict in the Middle East sending crude oil prices skyrocketing. However, the average also fails to reflect the significant price variation across states.
California retains its top spot as the state with the most expensive gas in the nation, with a gallon of gas costing $5.89, up $0.55 from just a couple of weeks ago. That beats out Hawaii, which sits at $5.46. Washington is the state with the third-highest average price at $5.38, up from $4.40 in February.
At the opposite end of the spectrum, drivers across the central and southern US are paying more than before, but still the least for regular gas. Oklahoma drivers now have the lowest average gas prices at $3.27. That’s up from $3.01 from mid-March. Kansas and Nebraska round out the top three states with the cheapest gas, averaging $3.31 and $3.41, respectively. Texans are paying $3.77, up rom $3.25, while Florida residents are paying $4.22, about $0.50 more than before.
The increase in the average price for a gallon of regular gas over the last month coincides with significant increase in mid-grade and premium prices, too. US consumers are now paying $4.58 and $4.94 for those fuel types, $1 more than a month ago.
Diesel customers are paying a whopping $5.49 a gallon on average, up $187 0 from a year ago. These trends offer a stark picture for consumers: Gas prices are rising.
