I decided to do the first oil change on my 2011 135i at 4k miles instead of the free 15k oil change. The oil was very black for only being a 4k miles. I couldn't imagine what it would look like at 15k.
I took many pics, but overall it is a very easy project it takes about an hour.
I got the oil and filter at my local dealer for $63

1) Start car and go for a short drive to let it warm up close to operating temperature. Then let car cool down for a little bit before draining.
2) Put car on ramps or jack stands:
3) Locate engine drain plug and remove it and let oil drain into drain pan. I decided to remove the entire undercover because I didn't want any oil mess. However as you can see in the pics there is a access plate for the drain plug.
4) Reomve Oil Filter. Be sure to note green marks and be sure they line up when reinstalling. I used Fram oil filter pliers with a microfiber cloth to avoid scratching.
5) Install new o-rings, oil filter and crush washer.
The imprints on the filter go inside the cap as shown:
Crush washer for drain plug supplied with filter;
6)Install oil Filter assembly:
7)Install drain plug: be sure old crush washer is not stuck to oil pan:
8) Add oil. I used about 6.7 quarts.
After adding oil drive the car for about 5 minutes and use the check oil function on the cars onboard computer to check oil level. Mine is at max.
Hope this helps anyone who decides to perform their own oil change.
