The national average price of gasoline has remained flat in February, fluctuating only a few cents for the month and reaching $2.29 per gallon on Feb. 27, reports AAA.

The price of regular unleaded is the same price it was a week and a month ago, and is 55 cents higher that it was a year ago. In about two weeks, prices are expected to increase as more refiners switch from the winter blend to summer-blend gasoline. Driver demand should also increase, according to AAA.

Federal data shows a similar trend. The national average price increased 1.2 cents to $2.314, which is 53.1 cents higher than a year ago, according to the U.S. Energy Information Administration.

The nation’s top five least expensive markets include South Carolina ($2.03), Alabama ($2.06), Tennessee ($2.07), Mississippi ($2.08), and Texas ($2.08). The nation’s top five most expensive markets include Hawaii ($3.10), California ($2.94), Washington ($2.75), Alaska ($2.74) and Nevada ($2.57).

The nation’s top five markets with the most dramatic weekly changes in prices include Indiana (down 10 cents), Utah (up 7 cents), Ohio (up 7 cents), Michigan (up 5 cents) and Idaho (up 5 cents).

Meanwhile, the average price of a gallon of diesel increased five-tenths of a cent to $2.577. Diesel is now 58.8 cents higher than a year ago.
