“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.”
