I was trying to do the "see how far I get on my first full tank" and I got down to the last bar on the fuel gauge but I was driving round a part of London I didnt know so I filled her up at the first petrol garage I came to. I think all in all I did about 265 on my first tank. Must have been a lot because most of that day was sat still in traffic jams. God bless London traffic jams
