Top up of tank and mileage covered gives me around 21 - 25mpg and I'm happy with that on BP Super Plus E5. The variation is directly proportional to the fun factor.
The cost and economy is a non issue for me, it's the unavailability of E5 that concerns me looking further down the road.
I'd be up for a Hydrogen conversion in a few years when it happens.
It's a right pain, towing that Zeppelin behind you
