The national average price of a gallon of regular unleaded gasoline increased 3 cents to $2.26 for the first increase in five weeks for the week ending July 10, according to AAA.

The moderate price increase comes during a week of solid demand growth and a third straight week of gasoline incentory drawdowns, according to AAA.

"Gas prices are still at some of the cheapest prices we’ve seen this year, but consumers should take advantage of them while they can," said Jeanette Casselano, AAA's spokesperson. "This week, drivers in 31 states are paying more than last week for a gallon of gas. And we expect to see slight price increases throughout July, so now’s the time to hit the road."

Indiana, Ohio, Michigan, and Kentucky saw double-digit price increases, while 13 states in the West Coast and in the Rockies saw incremental declines. Consumers can find gasoline for $2.25 of less at 58% of the country's gasoline stations.

The biggest weekly increases came in Indiana (15 cents), Ohio (15 cents), Michigan (13 cents), Kentucky (11 cents), West Virginia (7 cents), Delaware (6 cents), Kansas (5 cents), Oklahoma (5 cents), Nebraska (4 cents) and South Carolina (4 cents).

The least expensive markets now include South Carolina ($1.94), Alabama ($1.96), Mississippi ($1.98), Arkansas ($2), Tennessee ($2.01), Oklahoma ($2.01), Missouri ($2.02), Virginia ($2.03), Louisiana ($2.05) and Texas ($2.05).
