The average price of a gallon of self-serve regular gasoline in the Inland Empire rose today for the fourth consecutive day, increasing six-tenths of a cent to $4.128.
The average price in Riverside and San Bernardino has risen 3 cents over the past four days, including eight-tenths of a cent on Friday, according to figures from the AAA and Oil Price Information Service.
The average price is 3 cents more than one week ago, 1.2 cents higher than one month ago and 7 cents above what it was one year ago.
The rising pump prices stem from a sharp increase in wholesale prices caused by unplanned outages at two Los Angeles County refineries. The outages have disrupted Southern California gasoline production, reducing the supply, Marie Montgomery of the Automobile Club of Southern California told City News Service.
