The average price of a gallon of self-serve regular  gasoline in the Inland Empire rose Wednesday for the ninth consecutive day, increasing 1.5 cents to $3.70, its highest amount since Oct. 27.

   The average price in Riverside and San Bernardino counties has risen  10.8 cents over the past nine days and is 10.3 cents more than one week ago and 4.1 cents higher than one month ago but 43.6 cents less than one year ago, according to figures from the AAA and Oil Price Information Service.

   The rising prices are the result of reduced gasoline production amid refinery maintenance, according to the Automobile Club of Southern California.
