The average price of a gallon of self-serve regular  gasoline in the Inland Empire dropped to its lowest amount since Jan. 16 Wednesday, falling 1.4 cents to $3.688, one day after a 40-day streak of declines ended when it was unchanged.

   The average price in Riverside and San Bernardino counties is 5.3 cents less than one week ago, 22.1 cents lower than one month ago and 43.3 cents below what it was one year ago, according to figures from the AAA and Oil Price Information Service.

   The average price fell 31.1 cents during the streak. The dropping prices were immediately preceded by a 10-day streak of rising prices totaling 15.8 cents.

   The streak was the longest since a 52-day streak from May 22 to July 12, 2012.

   Further price decreases are expected because of lower demand and the switch to cheaper-to-produce winter blend of gasoline, according to Jeffrey Spring of the Automobile Club of Southern California said.
