So, I increased my range by over 50 miles (at one point it was 53 but I had to drive on a few twisties to find a petrol station)

Not bad MPG at all.

And apparently I was good for 750 miles after I filled up!
I am absolutely sold on the 50D, what a great all round machine. I certainly wasn't the slowest on the journey and in fact pretty much simply kept to the speed limits!
