Nobody can run on empty - our vehicles are no exception! So always leave at least 1/4 tank. (It’s on us!) This is really important for all journeys but especially for our Roundtrip vehicles as these vehicles are normally used for longer journeys and we need to ensure they are ready for the next member. Remember that topping up is free! If you’re running low during your reservation, use the fuel card at almost all UK petrol stations. Please note that you are not required to refuel if you are driving a Flex vehicle. We also take care of charging our electric vehicles – just be sure to stay in London to avoid running low on battery!
