My Napa doesn’t have it yet or if they do it isn’t on the shelf I know some of the oil you have to ask and they have it behind the counter. They have great oil for their house brand.
Yes, it's Valvoline, but still, it took awhile for the house brand to be available. Walmart offered 0w16 last year, and AAP has offered it for at least a year or two.
And last year's Napa sale on the name-brand Valvoline didn't include 0w16 (it was still full price), while AAP always included 0w16 in their sales as soon as they started selling their 0w16 (AAP/CQ oil is Amalie)
