When I got home I calculated that I probably only achieved about 63MPG - and I only had a 20 kilo load on board. I can only conclude that driving with more fuel than you need is very wasteful indeed.

Cheers again, Steve
I think it could also be that the wind direction was less favourable on the return trip - weight doesn't affect steady speed fuel economy much.
