I commute from Manchester to Huddersfield Monday to Friday and the best MPG I have achieved is 76.4mpg but that is driving 60-70 mph. The most I've had out of a full tank is 620 miles the range had gone to zero and I drove about 10 miles on zero range, when I filled it up I got 48.75 litres to brim so with that in mind I guess you could get 30 miles more when the range is at zero? MAYBE ?
