You will have an option of two different rental plans. One is the full-to-full plan, which means you will collect your rental car with a full tank of petrol and will need to return it with a full tank of petrol. Alternatively, you might prefer the same-to-same option, which allows you to refuel the tank to the level it was on when you collected it. This means that if you received the car with half a tank of petrol, you need to refuel it to that level upon returning it. Search rental cars on KAYAK
