The average price for a gallon of gasoline in the United States fell modestly over the past two weeks, ending a four-week advance, according to the Lundberg survey released on Sunday.
A gallon of regular-grade gasoline costs $3.26 on average across the United States, a decline of about 1.7 cents from two weeks ago, according to the survey taken on Dec. 20. The average is essentially unchanged from the $3.2579 average from the year-ago period.
"I think the decline will prove to be just a blip as there is a good chance that wholesale gas prices will creep up more than they already have, which would translate to pressure of a few cents quite soon,'' said Trilby Lundberg, publisher of the survey.
