But how do I calculate how much to add. Fill it up ?

There are two types of self-service fueling, one is credit card, the other is cash. Generally, 20 euros in cash is enough. Just follow the operation instructions to pay and pump fuel.
The last time I returned the car, I was at a gas station where I could fill up and then pay. It was on the side of the highway. In a situation like this, you can first add a small amount of gas, observe the fuel gauge, and then estimate how much more you need. It should be pretty close...haha.
