How do you know how much oil to add to the car ?

In general, car rental companies will tell you in advance, or there will be a mark on the inside of the gas tank.
Self-service fueling is almost non-existent in Greece, and the fueling is done by station attendants, who can accept cash or credit cards after the tank is full. The attendants will fuel your tank according to the oil grade indicated on the fuel cap.
