What drives the $2 spread between states?
- State and federal taxes. The federal excise tax is 18.4¢/gallon. State taxes range from ~9¢ (Alaska) to over 68¢ (California, including environmental fees). That alone accounts for most of the spread.
- Unique fuel blends. California and several metro areas require reformulated gasoline (RFG) — it costs more to produce and can only come from a narrow set of refineries.
- Refinery access & distribution distance. States far from the Gulf Coast refining hub pay more in transport costs. West Coast and Northeast refiners have fewer supplier alternatives.
- OPEC+ and crude oil. The single biggest lever. When Brent or WTI moves, retail prices follow within 1–3 weeks regardless of state.
