The average price of a gallon of self-serve regular  gasoline in the Inland Empire dropped today for the 10th consecutive day, decreasing 1.2 cents to $4.07.

   The average price in Riverside and San Bernardino counties has decreased 8.3 cents over the past 10 days, including eight-tenths of a cent on Thursday, according to figures from the AAA and Oil Price Information Service.

   The average price is 5.9 cents less than one week ago and 3.2 cents lower than one month ago but unchanged from one year ago.

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

   ``An improving supply situation has caused even more drops in wholesale prices and if the trend continues, we could see gas price averages drop below $4 a gallon in most areas in the next couple of weeks,'' Jeffrey Spring of the Automobile Club of Southern California said.

   ``We definitely recommend that drivers should shop around and look for gas stations that are currently charging less than $4 a gallon.''
