One thing to be aware of is that the small (hex#6) drain plug in the oil filter may be hard to remove. It was last time on mine. My indie mechanic decided to just remove the whole plastic filter cover rather than possibly stripping the plug insert. He thought that was better than risking the local dealer being out of stock of the replacement cover.

Also, when you remove the main drain plug, as stated in the write-up on Xoutpost, the flow of oil is very strong. When I got my 20" wheels, my indie came over to help install them and do an oil change. The oil drain pan I purchased was a combo drain and container. It couldn't keep up with the flow from the X5 and made a big mess. It was fine with our smaller vehicle. Similar to this one:

I recommend that you clean around and inside the metal cover that protects the oil pan with some shop rags. Otherwise, you will likely have some oil dripping out of it for a few days.
