What fuel options do you offer?

National offers three fuel payment options: 1. Refuel before returning: Replace the fuel you used so the vehicle is returned at the same fuel level as when you collected it. 2. Prepay at pickup: Purchase a full tank at the start of your rental and return the vehicle without refilling it. The estimated charge depends on current fuel prices and the average tank size for your reserved vehicle class; the final charge may change at pickup. 3. Pay on return: National charges for fuel used but not replaced. The per-gallon or per-litre rate is higher than local pump prices.
