Or SOPUS just buys too many at once and doesn't want to waste them. For most North American and Japanese cars, SM/GF-4 is enough. Aside from that, they're aware that it's mostly BITOGers that read the labels anyway.
Realistically, if someone with a GM with a dexos1 requirement has a warranty problem, and the dealer or GM asks for receipts, the receipt might say Pennzoil Platinum 5w-30. It's not going to say anything about dexos1 or which API and ILSAC specs the oil met. They're not going to be asking for empty bottles. If the receipts were to say M1 5w-30 or PP 5w-30 (or any other dexos1 licenced oil), I'd suspect that would be sufficient.
