The national gas price of unleaded gas raised by one cent to $2.54 from last week, as demand for gasoline for the month of January decreased modestly, though the amount of inventory increased, according to AAA.

Gasoline increased to 3.6 million barrels, according to the Energy Information Administration.

“Since 2014, gas prices decreased as much as 20 cents in the first three weeks of the year. This year, gas prices are five cents more than on January 1 of this year, a possible indication that prices in 2018 will likely be more expensive than last year,” said Jeanette Casselano, AAA spokesperson.

States with the largest yearly changes includes California (up 39 cents), Indiana (up 37 cents), Michigan (up 32 cents), Alaska (up 30 cents), Oregon (up 28 cents), Hawaii (up 28 cents), Montana (up 28 cents), Ohio (up 27 cents), Illinois (up 25 cents) and Tennessee (up 25 cents).

States with the least expensive gasoline include Texas ($2.29), Missouri ($2.30), Alabama ($2.30), Mississippi ($2.31), South Carolina ($2.32), Arkansas ($2.32), Arizona ($2.34), New Mexico ($2.35), Oklahoma ($2.35) and Tennessee ($2.36).

Gasoline is available for $2.50 or less at 58% of gas stations nationwide, according to AAA.
