I would believe that most if not all comes from a bulk tank unless you would request for something that is not normally carried on site. Also Jiffy Lube is a franchise so you pay a 4% royalty to Jiffy Lube as a franchise owner you could use any oil you choose that is why some Jiffy Lubes offer Quaker State, Lucas, Pennzoil, Formula Shell, I have even hear of some offering Mobil One. But I suspect you would get a discount offer from SOPUS to use one of their products, but it is the owners choice.
