PORTLAND, Maine — The average price of a gallon of regular gasoline ticked up again in the past week, bringing prices on par with last fall from lows hit this winter.

The price tracking website GasBuddy.com reported the average price in Maine jumped about four cents in the past week to $2.09. The national average rose two cents to $2.06, over the same period. Both prices are more than 25 cents higher than one month ago and around 31 cents lower than a year ago.

Will Speer, an analyst for GasBuddy, said prices are expected to continue rising this week but that refineries have almost completed their switchover to the more expensive summer blend.

“Southern California was the first region in the United States to complete the summer-blend switchover on Friday, while the rest of the United States follows suit at the end of the month,” Speer said in a news release.

He said increasing refinery output through March helped curb some of the price increases related to the summer blend switch.

The average price in New Hampshire for regular gasoline was $2 per gallon. It was $2.09 in Vermont.
