The average price of a gallon of self-serve regular gasoline in Los Angeles County rose Friday for the 21st consecutive day, increasing a half-cent to $4.171, its highest amount since Oct. 21, 2019.
The average price has increased 14.5 cents over the past 21 days, including six-tenths of a cent on both Wednesday and Thursday, according to figures from the AAA and Oil Price Information Service. It is 4 cents more than one week ago, 19 cents higher than one month ago and $1.308 greater than one year ago.
The average price has risen 93.9 cents since the start of the year, mainly because of a run of 59 increases in 60 days totaling 57.9 cents that ended March 21.
The Orange County average price rose for the 17th time in 18 days, increasing four-tenths of a cent to $4.13, its highest amount since Oct. 21, 2019. It has risen 12.2 cents over the past 18 days, including eighth-tenths of a cent Thursday.
The Orange County average price is 3.2 cents more than one week ago, 17.7 cents higher than one month ago and $1.313 greater than one year ago. It has risen 92.2 cents since the start of the year, mainly because of a run of 72 increases in 73 days totaling 68.1 cents that ended March 20.
The large price increases from one year ago are the result of significant decreases during the early stage of the coronavirus pandemic, when driving and demand dropped substantially because of stay-at-home orders intended to reduce the spread of the virus.
A more appropriate comparison would be with the average prices from two years ago. The Los Angeles County average price is 10.5 cents more than it was on May 13, 2019, while the Orange County average price is 9.6 cents more.
