Gas prices

   LOS ANGELES   - The average price of a gallon of self-serve regular gasoline in Los Angeles County rose four-tenths of a cent today to $4.223, one day after recording its largest daily increase since May 6, 1.2 cents.

The average price has increased 34 of the past 37 days, rising 19.7 cents to its highest amount since Oct. 16, 2019. It is 3.7 cents more than one week ago, 14.8 cents higher than one month ago and $1.277 greater than one year ago.

The average price has risen 99.1 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 two-tenths of a cent to $4.175, one day after recording its largest daily increase since May 6, 1.4 cents. It is 3.4 cents more than one week ago, 12.9 cents higher than one month ago and $1.258 greater than one year ago.

   The Orange County average price has risen 96.7 cents since the start of the year to its highest amount since Oct. 17, 2019, 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.
