The oil change is a bit more challenging but not hard. The main issue is room under the car. Really wish I had a lift, it would be easy.
There are five silver bolts behind the front splitter, that hold the front of the belly pan on. 10mm bolts. Remove the five silver bolts. There are another 10 or so black 10mm bolts that hold the pan on as you work back. An angle driver / drill works great.
There are two friction / push in pull out plastic attachment points at the very back of the pan. The previously mentioned pry tool worked great.
Once you get the pan out of the way, there are two drain plugs. They are both 15mm and easy to get at with a socket wrench. I pulled the one towards the front first and most of the 10qts came out. Pulled the 2nd and a bunch more oil came out. The oil filter is right there. A 76mm Oil Filter Cap Wrench is the perfect tool.
I had to go with a Mobil 1 filter but it looked identical to the standard filter.
It took all 10qts. I think it would take another 1/4 quart. Costco has the Mobile 1 5w/30 oil.
