Excuse me, how do I self-service gas up in Europe ?

Drive directly to the gas station in the Netherlands and ask clearly what types of oil can be added when picking up the car. After filling it up by yourself, go to the gas station store, report the fuel number and pay the money. Cash and credit cards are both acceptable.

The self-service petrol order in Denmark and Sweden is as follows: insert card, enter password, confirm, remove card, choose fuel, end petrol, hang gun, insert card, print invoice
