Knocked this car out tonight. Simple oil change and inspection was due. Mmmm pretty. After removing the oil filter housing, there are 2 o-rings to replace along with the filter. When you pull the filter, you will want to suck out the remaining dirty oil. And to drain the oil, underneath a trap door, is the 17mm oil drain plug. Drain the oil, replace the copper drain ring, and fill with some fresh BMW longlife 5w-30 🙂 Weeeeeeeeee!
