To answer your question, the $49 synthetic oil change won't be Supertech, it'll likely be Mobil 1 or Castrol Syntec... maybe Pennzoil Platinum. But it will be out of an Eco-box. For $5 more you can get a bottled oil of your choice, as long as WM stocks it. Mobil 1 EP for example or Castrol Titanium.
The filter will be a 'Fram'(e)core. You'll probably want to upgrade to a better filter, especially if you're getting synthetic. If you want the Bosch, you'll get a $2 credit towards it. Just make sure the service writer knows this.
And like others have said: Watch them!
They'll probably have to go into the store to get the filter (and/or oil), so you'll know if they get what you want.
