How often do you service your X5?

Is this because we are "told" that motor oil is only 'good' for a six months period?
I have several cars that rarely get driven (summer cruisers) and sit in a garage most of the year. I choose to change the oil in them on an annual basis. On average, these vehicles would only travel about 5K kms a year though.
I believe oil has a limited 'shelf-life' and will deteriorate with time, both in an unopened container and in an engine.
