RIVERSIDE, Calif. -

The streak of decreases to the average price of a gallon of self-serve regular gasoline in the Inland Empire was extended today to a 14th day, but barely, with a decrease of one-tenth of cent to $4.036.

   The average price in Riverside and San Bernardino counties has decreased  1.3 cents over the past 14 days, including 1.4 cents on Monday, according to figures from the AAA and Oil Price Information Service.

   The average price is at its lowest amount since April 4 and 6.3 cents less than one week ago, 6 cents lower than one month ago and 3.3 cents below what it was one year ago.

   The streak of decreases was immediately preceded by 11 increases in 14 days; they pushed the average price to its highest amount since May 19.

   The dropping pump prices stem from continuing decreases to the wholesale price caused by an improving supply situation, according to Jeffrey Spring of the Automobile Club of Southern California.
