The average price of a gallon of self-serve regular gasoline in San Diego County rose six-tenths of a cent Thursday to $4.03, one day after a 22-day streak of decreases ended with an increase of three-tenths of a cent.

The average price is 3.6 cents less than one week ago and 4.1 cents lower than one month ago, but 23.8 cents higher than one year ago, according to figures from the AAA and Oil Price Information Service. It has risen 68.9 cents since the start of the year.

The increases follow rising wholesale prices “related to unexpected breakdowns” at the Chevron refinery in El Segundo, the Phillips 66 refinery in Wilmington and the Shell refinery in Martinez, according to Marie Montgomery, a public relations specialist with the Automobile Club of Southern California.

The average price dropped 18.5 cents during the streak to its lowest amount since Sept. 28. The decreases followed a run of 19 increases in 21 days which pushed the average price to its highest amount since July 20, 2015.
