Could be anything running the gambit from bulk, delivered by the truckload tote 5W-30 / 10W-30 dino with no ratings. To top shelf synthetic oils. Dealers have been known to cut corners, especially on an item like oil changes which are viewed as a 'loss' activity to get people in the door.
In fairness, quickie lubes and even independent garages are known to cheat. A certain brand that was well known for diesel cars apparently had dealers who couldn't even, for a while, obtain and sell the "official" oils to the public, so it was an almost certainty that they weren't using them themselves.
