The most common fuel policy for car rentals is "Full to Full", which means that the vehicle will be given to you with a full tank of fuel and you will have to return it with a full tank as well. To avoid any additional charges, make sure to return the vehicle with the same amount of fuel as it had when you received it.
During the pickup, you may be required to leave a fuel deposit or have it charged on your credit card, which will be refunded or released when you return the car with a full tank. If the vehicle is not returned with a full tank, missing fuel will be charged at a higher rate than the local service station and a refuelling fee may also apply. These charges will be payable at the rental desk unless otherwise stated in the rate details.
