The average price of a gallon of self-serve regular gasoline in Los Angeles County rose 3.4 cents Wednesday to $3.836, the ninth consecutive increase.
The average price has risen 16.4 cents over the past nine days, including three-tenths of a cent on Tuesday, according to figures from the AAA and Oil Price Information Service. The cost of a gallon of gas is 7.8 cents higher than one week ago, 26.3 cents higher than one month ago and 11.4 cents greater than one year ago. It has risen 44.5 cents since the start of the year.
The Orange County average price rose 5 cents to $3.804, one day after remaining unchanged. It has risen 16.8 cents since Sept. 17, including 7.5 cents last Wednesday, its largest increase since July 14, 2015.
The Orange County average price is 7.7 cents more than one week ago, 25.8 cents higher than one month ago and 12.9 cents greater than one year ago. It has risen 45.5 cents since the start of the year.
The Wednesday increases are the result of a 20% decrease in the gasoline supply from last week caused by incidents at Los Angeles-area refineries operated by Chevron and Marathon Oil and “a lack of imports” to compensate for the decrease, according to Marie Montgomery, a public relations specialist with the Automobile Club of Southern California.
“Imports take time to reach us because they all have to come by ship” from Asia, Canada and other locations, Montgomery told City News Service.
The start of the run of increases was the result of increasing oil costs caused by the attacks on Saudi Arabian oil facilities, Montgomery said.
