I've compiled the results for 2012 from the Post your latest oil change thread.
Just a few notes:
Mobil 1 includes all variations of Mobil 1. I felt that they were all to similar, so I didn't try to separate them.
Also, I didn't include any oils that were only used once.
When brands are combined, Mobil tops the list for 2012 at 223 oil changes, followed by Pennzoil at 168, and Valvoline at 127.
