180 miles a litre is not normal. Of course itís all subjective so it will depend on your type and style of driving. To get that high on usage I would imagine you are doing lots of low mileage trips and the engine isnít getting up to temperature.
If not, I would get everything checked out. It seems a 10 litre top up lasts around 4K miles averagely from my reading on here.
