I might be miles out, but the wife's old Bora used to have an emergency tank. If the main tank ran out, it ran on the emergency for upto 40 miles. Never quite understood the point of it?FriendlyWombat said:iamdabe - i'm sure I read in the manual somewhere that the tank holds an "emergency" 40 miles in it. Or something along those line.I guess that might be where the petrol dial and actual fuel going in could be different. Still, I would not expect it to be as much as that.
