That is the best reason for changing the factory fill out as soon aas you pull it in the drivway
LOL! I about spewed my soda on the keyboard with that one!
In reality, I bet E/M is probably giving away the oil on some of these Mobil 1 factory fills. In return, the auto manufacturers put a little "Mobil 1 factory fill" sticky somewhere on or near the engine. I'd say follow the money trail, but if it's free, there probably isn't a money trail.
