500 miles is achievable in Summer with my 1.7 diesel MPV but its a boring drive with danger of falling asleep at the wheel. ?? Otherwise mostly around 400 miles per tank with a 55 Litre Tank and around 380 in Winter. Mostly suburban and city driving.
on a boring drive back from Wales last August I managed to get 56mpg so it was a nearly 500 mile run on one tank.
