Changed my oil and filter using Mini 5-30w oil, seems to make my engine quieter than when I use Mobil 1. The air filter had about 10,000 miles on it and it wasn't too dirty, more deformed than anything else. Tire rotation is easy as seen in this picture, just lift the front and the rear comes up too.

 

Tell me you used jack stands on that rear during the rotation haha. Also you just switched front-back not side to side right? Since you have aftermarket tires I guess directionality isn't an issue
