The national average price of a gallon of regular unleaded fuel remained flat at $2.66 when compared to last week, the highest price so far this year, according to AAA.

However, fuel prices are fluctuating from state to state, with increases of up to 12 cents and declines as low as 7 cents, reports AAA. Indeed, Utah, Idaho, and Wyoming saw the largest increases by 12 cents, 9 cents, and 3 cents, respectively.

The current fuel price average resulted from an 11 cent jump in the two weeks preceding last week as fuel stations were purging their winter blend gasoline.

“Gas prices are only a penny away from topping the $2.67 high of 2017,” said Jeanette Casselano, AAA spokesperson. “The price is likely to increase as spring brings warmer weather and the switchover to summer blend gasoline, but hopefully we will only see mild jumps in coming weeks.”

States with the largest yearly increases included California (up 54 cents), Hawaii (up 47 cents), Idaho (up 44 cents), Utah, (up 42 cents), and Arizona (up 40 cents). Meanwhile, states with the most expensive markets include California ($3.52), Hawaii ($3.52), Washington ($3.19), Alaska ($3.17), and Oregon ($3.10).

The average price of a gallon of diesel increased .001 cents to $3.043, which was 46.1 cents above a year ago.
