Assuming the OP isn't a troll, let's review:
She doesn't trust the dealership to use the right fluids and filters so she brings her own, effectively adding $50 to the cost of the oil change.
She does, however, trust the dealer enough to pay them to tell her that it has cooler outside and you can see the exhaust plumes.
If she is actually serious, then she needs to either do the oil changes herself (but then we'll get the posts that say "why is my oil pink and so thin?") or find a reliable independent - or her boyfriend can do it using that "vacuum thingie"
While I've seen dealers use bulk oil, I've not seen one use non-OEM filters and VW frowns on dealers using bulk oil that doesn't meet specs - ask me how I know (or better yet, ask the ex-GM and ex Service Manager at Audi of Rockville)
