Regular gasoline in California averages $5.43 per gallon as of the EIA week of 2026-08-10 — $1.42 above the national average of $4.01. Diesel averages $6.62 per gallon. California has the nation's highest state fuel taxes and fees (over 68¢ per gallon), requires a special low-emission CARB gasoline blend that few refineries outside the state can produce, and its cap-and-trade and low-carbon-fuel programs add further cents per gallon. With limited pipeline links to other regions, local refinery outages can spike prices fast.
