Dealership oils

I just took a car into the dealership for an oil change, covered under ToyotaCare.
If Toyota pays, it’s TGMO 0W-20/16/8 and the RO is billed for that.
Customer pay, my local dealership pours bulk Havoline 5W-30/0W-20 ProDS.
 
I worked for a dealer for 15 years was a Toyota and Lexus master tech. We used wolf’s head bulk oil for the average oil change. If it was anything other than that. Say even a valve cover gasket and oil change it got billed to the customers as Toyota oil and you would get the actual quarts of Toyota oil. Why? It was more profitable to just sell the cheap oil for just oil changes and bang the customer for the Toyota oil on any other work. I never liked doing it but that’s what it was.
 
Is there a running thread keeping up with what manufacturers dealer oils are? (I did search but found not much) If not, would it be informative to have one?

For example, we know subaru is Idemitsu oil. I think a fee other japanese cars are, too.

Maybe we could include UOA if we get them too.

The reason I'm asking: I'm curious what Hyundai/Kia uses for their dealer/bulk oil since we plan on sticking with the oem services for my wife's 2024 seltos that gets about <4k miles per year.
My last truck was a 2015 Ram 2500 w/6.4L Hemi. It had the lifetime powertrain warranty, so I had the dealer do my oil & filter changes the first few years. I'd watch them refill the oil with Pennzoil Ultra Platinum 0w-40 in one-quart bottles just like you'd buy in a parts store.
