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, 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.
