I'm using 15w40 as per BMW's instructions. The only reason I would see in using a 5w30 or thinner is to have the engine running smoother in winter.

After about 2 weeks of owning my car, I checked the oil one night and I was just at the bottom, so I decided to get 15w40 MotoMaster Synthetic oil and so far so good!
