Why does San Francisco always have the most expensive gas?
SF combines California's maximum tax burden, extremely high real estate and labor costs for station operators, CARB fuel premiums, and strong environmental surcharges. A station in SoMa pays vastly more in rent and labor than one in Fresno — and those costs go directly into the pump price.
