Self-service

Self-service is standard: pull up to the pump, pay at the pump by card or prepay inside, then fill up yourself. Many stations — especially overnight — won't switch the pump on until you've paid. Fuel is priced per US gallon, and a regular fill is right for almost every rental.

Latest EIA weekly figure in USD per US gallon; some states show their PADD regional average. Compare every state on the fuel-price map, or read the full guide to refueling in the USA.
