I need to do my first oil change. I know the car takes 8 quarts of synthetic oil. I am not sure of the weight. Besides BMWs own synthetic what else is a good one to use? Mobil 1, Castrol, Valvoline or some other brand? Also, exactly where is the oil filter located and what else needs to be done besides resetting the service gage? I don't have a Bently manual for this car yet so any help would be appreciated.
