alternatively (sorry to turn the direction of this thread) but whats ur worst???

although many factors can attribute and it's a stupid figure
but i'd still like to see what people have done

I've hit as low as 280 from a tank once (from memory)
since then i've had a few things done to the car and i think it's average/just below avg economy now in normal circumstances.

cuz everyone talks about how much they can squeeze out of a tank and no one talks about how little.
