Don’t really do the MPG thing and tend to base averages off of overall distance per tank travelled regardless of type of roads, but in general my 32 mile round trip commute four days a week and minimal weekend pottering about will see a tank return of around 500-520 miles.
I did however do a long run last week; Glasgow to South Wales and back which saw 620 out of one full tank and the overall distance was 938 miles. I had a gnats chuff just under half a tank left when I got home so pretty pleased considering it’s a 2009 318i petrol and not diesel. 600 on long motorway runs is fairly easily achieved when sensible.
