The average price of a gallon of self-serve regular gasoline in Los Angeles County dropped one-tenth of a cent this week to $3.332, ending a run of 12 increases in 13 days totaling 7.5 cents.

The average price is eight-tenths of a cent more than one week ago and 2.9 cents higher than one month ago but 9.5 cents less than one year ago, according to figures from the AAA and Oil Price Information Service.

The run of increases followed an eight-day streak of decreases totaling 5 cents that dropped the average price to its lowest amount since Jan. 20, 2018.

The Orange County average price rose one-tenth of a cent to $3.298, one day after dropping one-tenth of a cent. It is unchanged from one week ago, 3.5 cents higher than one month ago but 9 cents less than one year ago.

“We are hearing from oil industry analysts that the California rainstorms have depressed gasoline demand and that once the Chevron El Segundo refinery came back online fairly quickly after its power outage caused by lightning, supply concerns seem to have been eliminated,” Marie Montgomery of the Automobile Club of Southern California told City News Service.

“Unfortunately at the moment that has not translated into much of a price drop because refineries are already producing the summer blend of gasoline, which is more expensive, but at least pump prices are not still rising as they were last week.”
