Rental car fuel policies: full-to-full and prepaid fuel explained

Full-to-full is often the easiest policy to understand: collect with a full tank and return it full. Other offers may use same-to-same or prepaid fuel with service charges. Compare the complete terms, not only the rental price, and keep a nearby refuelling receipt.

At a glance: what to check before booking

  • Identify the policy before booking
  • Check and photograph the gauge at pickup
  • Refuel close to the return location
  • Keep the final fuel receipt

Common fuel policies

Full-to-full requires a full return, while same-to-same expects the original level. Prepaid arrangements may charge for a tank or service in advance and may not refund unused fuel.

The cheapest daily rate can become less competitive after fuel and service charges, so compare the total arrangement.

What to do at pickup

Confirm that the gauge matches the handover document and photograph it before leaving. Ask how the supplier defines a full tank and where discrepancies should be reported.

Avoiding a fuel charge at return

Use a station reasonably close to the return point, retain the receipt and photograph the gauge. Leave enough time because airport fuel stations can be busy or difficult to reach.
