I've been keeping an eye on my fuel consumption graph in my
garage and I've noticed that the FE has dropped very slightly over time from June until now. I've covered 35,000 miles since April '09 and now my car has 97,000 miles on the clock - is it possible that age/wear & tear on either the engine or the car itself would increase consumption slightly over time, or could it be something else? Or is it just a blip? I haven't done anything on the car since August apart from oil changes, and I've used the same oil since buying the car.
After all, I used to have 3.7 L/100km but now I get 4 L/100km :-/
