I'm in agreement with the others here. On my 2011 X5 with the N55 engine I changed it once a year at about 7500-10000 miles. It was a lease but it still bothered me to no end as I've always been one to change the oil every 5K with full synthetic (sooner than that I think is a waste unless your really driving it hard).

On my wife's new 2013 X5 I'm changing it every 5000-7500 MAX, as I too don't put that many miles on our cars.

My 2015 650 I plan to change the oil every 3000-5000 miles as well as it probably won't be driven that many miles each year anyway (Chicago weather).

As others have mentioned, if your planning on keeping the car and want to keep it running it's best, every 5000 miles is a good average for the new synthetic oils that they put in them.

In the end, it's kind of cheap insurance.
