The average price of a gallon of self-serve regular  gasoline in the Inland Empire recorded its largest daily increase since Feb. 16 Wednesday, rising 2.3 cents to $3.92.

The average price in Riverside and San Bernardino counties has risen  five consecutive days and is 3.7 cents more than one week ago, according to  figures from the AAA and Oil Price Information Service.

However, thanks to 28 decreases in a 31-day span before the increases  began, the average price is 11.1 cents less than one month ago and 28.1 cents  lower than one year ago

The increasing pump prices follow a rise in wholesale gasoline prices  which analysts attribute to record low stockpiles of gasoline stemming from a  drop in production caused by both scheduled refinery repairs and unplanned unit  shutdowns.
