The cars must be returned with a full tank of gas. If not, the rental car agency will refill the tank and charge for the service. It is often cheaper to fill the tank at a local gas station before returning the car than to pay the rental company's per-liter rate.
The minimum rental period for standard cars is one day, and for minivans, it's two days. This period may increase based on seasonal demand and vehicle availability. To confirm the exact minimum rental duration, please search for your intended dates.
