County gas price average increases for 12th straight day

The average price of a gallon of self-serve regular gasoline in San Diego County increased 1.6 cents Sunday to $6.141, its highest amount since Oct. 4, 2023.

The average price has risen 12 consecutive days, increasing 28.9 cents, including 2.2 cents Saturday, according to figures from AAA and Oil Price Information Service. The streak of increases follows a 13-day streak of decreases totaling 11.7 cents.

The average price is 15.4 cents more than one week ago, 20.3 cents more than one month ago and $1.403 more than one year ago. It has risen $1.455 since the joint U.S./Israel attack on Iran Feb. 28, moving within 29.4 cents of the record $6.435 set on Oct. 5, 2022.

“California’s gasoline supply is significantly affected by the Strait of Hormuz closure,” Kandace Redd, the Automobile Club of Southern California’s senior public affairs specialist, said in a statement released Thursday.

“According to the California Energy Commission, in 2025 the state relied upon Middle East countries for 29% of the oil it used in the state’s refineries to produce gasoline. Additionally, the gasoline that California imports from refineries in other countries is also heavily reliant on oil from the Middle East.”

The national average price rose 1.3 cents to $4.446, its highest amount since July 20, 2022. It has risen 11 consecutive days, increasing 42.6 cents, including 4.1 cents Saturday. The national average price is 34.7 cents more than one week ago, 35.5 cents more than one month ago and $1.275 more than one year ago. It has risen $1.464 since the attack on Iran, moving within 57 cents of the record $5.016 set June 14, 2022.
