About gas prices in California
California has the highest gas taxes in the nation at roughly 60 cents per gallon when you combine the state excise tax with the cap-and-trade program and underground storage fee. The state requires a special CARB-formulated fuel that only a handful of in-state refineries can produce, so a single refinery outage can spike prices statewide within 48 hours. Costco, Sam's Club, and Arco are typically the cheapest across Los Angeles, San Francisco, San Diego, and Sacramento metros, while Chevron, Shell, and 76 dominate freeway exits. Stations along Interstate 5 and US 101 commonly run 10 to 20 cents higher than equivalent stations a mile off the freeway.
