I never really think about it. When I worked at Sears, they only used a certain kind of oil, and it wasn't the cheap stuff. Sure, it was bulk oil, but the bulk oil was Castrol GTX in 2 or 3 viscosities. I think we had 10W30, 5w30, and 10w40 at that store. The filters are an off-label Wix filter, same thing as Fram, IIRC.

Really, there's nothing cheap about the oil change for Sears, besides the fact that they're making money because of the bulk they buy the stuff in. They're also supposed to top off your wiper fluid, check/grease your chassis/suspension (if applicable) and make recommendations about tire wear and rotation, all as part of the oil change service. They also paid something like $1.80 commission for the oil change, not based on time, but based on completion. I used to do like 4-5 an hour, on top of my normal $9.00/hr paycheck. I had more income than the Alignment Technicians at times, based on work load. And I almost never had to work.
