When using CityBee, you do not need to pay for the fuel - you will pay only for the time used and for kilometers driven.
When the fuel drops to 1/4 volume of the tank capacity, go to any Circle-K gas station in Lithuania and fuel the bee. Fill a full fuel tank and pay with the gas stations' card which you will find in the CityBee car at the sun visor on the top of the driver’s side.
You will find the payment card PIN code in the CityBee app after opening your active reservation. You will find stickers indicating the type of fuel for a car on the sun visor and the fuel tank cover (both inside and outside).
