Los Angeles County gas prices saw their largest daily spike since Feb. on Friday as the average price of a gallon of self-serve rose 3.7 cents to $3.904.
The increase marked the 15th day of consecutive daily increases. It pushed the average price 16 cents higher than one week ago.
The average price of $3.904 is 8.8 cents above where it was one month ago, and 86.3 cents more than it was this time last year, according to figures from AAA and the Oil Price Information Service.
The Orange County average price rose Friday by its largest amount since March 4, 3.6 cents, to $3.891, the highest since June 20. The Orange County average price has also increased for 15 consecutive days and is 15.8 cents more than one week ago, 9 cents higher than one month ago and 85.4 cents higher than at this time last year.
"Gas prices have gone up around the country over the past week, but not by double digits as we've seen in California,'' said Jeffrey Spring of the Automobile Club of Southern California.
"Refinery issues are being blamed for the spike and unfortunately that means holiday travelers will be paying prices for their Labor Day fuel that are near or beyond what they paid in 2008, our record-breaking year for gas prices.''
