Thanks Chaps.....very useful
I need to check what kinda mileage/range the other guys in our group will enjoy before I decide whether I will resign myself to being unpopular or not.
Viper - do it! If you don't you'll be kicking yourself in the arse because of the missed opportunity which by itself far outweighs the risks you have identified.
If you are worried about the mileage - pamper her. If you want to lead the pack you might have to pull over, refill and then once again do a Bonzi run to regain past status in the pack.....
so whats the problem? :confused
