You should use CASTROL Fully Synthetic 5w-30. Use either castrol or buy it from the dealer. BMW manufacturers recommend castrol. in fact, i think that is what they use. Always use "fully synthetic."

Trust me on this. after i changed the oil, the car was a little bit quicker. it was noticeable for sure.

drive your car before and after you change the oil so that you can feel the difference.
