While I realize the owners manual specifies an AC Delco filter, I thought that technically the OEM filter would have a GM part number.

My 2013 Silverado had as AC Delco PF48 oil filter on it from the factory.
I think my dad's '96 Buick Regal Custom had an AC PF47 too, but I was under the impression that there are still some non-AC GM part numbers. I don't think I've ever seen one, but they exist somewhere. Something like this:
There's a whole bunch of GM numbers in cross-reference guides, but I don't recall ever seeing one. I've been to a Buick dealer and I might have asked for an oil filter and passed when I saw an AC. Over the years I bought a lot of AC (later ACDelco) filters, and I remember ones that were labeled as AC Rochester, Delphi, GM UK (had a ridge around the circumference of the filter), and obvious Champion Labs ones.
