A 22-day streak of decreases that pushed the average price of a gallon of self-serve regular gasoline in San Diego County to its lowest amount since Sept. 28 ended Wednesday with an increase of three-tenths of a cent to $4.024.

The average price dropped 18.5 cents during the streak, including eight-tenths of a cent on Tuesday, according to figures from the AAA and Oil Price Information Service. The decreases followed a run of 19 increases in 21 days which pushed the average price to its highest amount since July 20, 2015.

The average price is 5.7 cents less than one week ago and 4.7 cents lower than one month ago, but 22.5 cents higher than one year ago. It has risen 68.3 cents since the start of the year.

The increase follows 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.
