The average price of a gallon of self-serve regular gasoline in Los Angeles County set a Labor Day record Monday of $4.173, erasing the previous record of $3.958 set last year.
Analysts attribute the record to the Aug. 6 fire at the Chevron refinery in Richmond, which reduced its refining capacity and supplies.
The all-time record is $4.626 set on June 21, 2008 when investors were bidding up the price for crude oil to a record high as the dollar was declining in value.
The average price was unchanged Monday, ending a 10-day streak of increases that pushed the price up by 5.4 cents, including four-tenths of a cent on Sunday, according to figures from the AAA and Oil Price Information Service.
The average price is 3.6 cents more than one week ago, 31.4 cents higher than one month ago and 23.7 cents greater than one year ago.
The Orange County average price also reached a Labor Day high Monday, increasing two-tenths of a cent to $4.155, erasing the previous record of $3.939 set last year.
