Gas prices exceed $5 a gallon at some Los Angeles area stations

As gas prices reached its highest level in the state of California since 2015, some Los Angeles area gas stations are charging more than $5 a gallon.

The average price of a gallon of self-serve regular gasoline in Los Angeles County was $4.25 on Wednesday, according to figures from the AAA and Oil Price Information Service. The average price is 4.5 cents higher than one week ago, 57.6 cents more than one month ago and 37.1 cents greater than one year ago. It has also risen 86.4 cents since the start of the year.

Gas prices began increasing rapidly last month after Saudi Arabia oil production facilities were attacked, and the increases sharpened after three Los Angeles-area refineries slowed or halted production due to maintenance issues and no imported gasoline was available to make up for the shortfall, according to Jeffrey Spring, the Automobile Club of Southern California's corporate communications manager.

Local refineries had already cut back production of summer-blend gasoline in anticipation of switching to selling the winter blend beginning Nov. 1, creating even more of a shortage.
