Why is my 5 Series using so much oil?

I recently purchased an extremely low mileage 2007 BMW 5 Series. What is BMW's thinking about oil usage which is between 1/2 and 1 litre per 1000 miles? It is obviously designed to consume this ammount
Probably caused by the way the car has been driven. A life of short runs from cold starts pours a lot of petrol into the oil with a detrimental effect on bore wear. I'll bet this has only had oil change services every two or three years when it really needed them every year.
