I was out in the sticks today when I realised the tank was nearly empty. I limped to the local garage, 5 miles away, coasting part of the way with the engine off (not recommended for safety reasons, but it was a quiet country lane). A few miles from the garage and the needle was on zero, but I made it, somehow. 36 liters went in, with 452 miles elapsed, giving 57mpg. Apparently the tank holds 35 liters. Eh? No it doesn't, it holds at least 36 liters.
