About filling up at gas stations
Both full-service and self-service gas stations are available. At full-service stations, follow the guidance of staff. At self-service stations, you will have to take care of everything yourself.
Hints for filling up
Make sure you get the right kind of gasoline (high-octane = haioku, regular = regyuraa, diesel = keiyu)
Mantan = fill up the tank
Genkin = (pay in) cash
