LOS ANGELES (CNS) — The average price of a gallon of self-serve regular gasoline in Los Angeles County was unchanged Monday at $6.098, a record high, after rising one-tenth of a cent a day ago.

The average price is 6.9 cents more than one week ago and 31.1 cents higher than one month ago, mainly as the result of a 22-day streak of increases totaling 32.3 cents that ended Friday, according to figures from the AAA and Oil Price Information Service. It is also $1.912 greater than one year ago.

The Orange County average price dropped one-tenth of a cent to $6.071, a day after reaching as record high of $6.072. It is 5.8 cents more than one week ago, 34.3 cents higher than one month ago and $1.93 greater than one year ago.

The Orange County average price increased 32.3 cents during a run of 21 increases in 22 days that ended Friday.

The national average price rose three-tenths of a cent and reached a record high at $4.596.

“Tighter supply and increased demand have pushed pump prices higher,” Doug Shupe, the Automobile Club of Southern California’s corporate communications manager, told City News Service on Sunday. “This supply/demand dynamic, combined with volatile crude prices, will likely keep upward pressure on pump prices.

“We don’t see any immediate relief in sight due to the global oil concerns exacerbated by the war between Russia and Ukraine and the increasing demand for gas as drivers prepare to take summer road trips beginning Memorial Day weekend,” he said.
