Pennzoil Ultra Platinum 0W-40 availability.

New York
Does it actually show the MS 12633 spec on the back label?

The ones I've seen on Walmart's website do not show it. I thought maybe because it was just old stock (prior to obtaining the MS 12633 approval), but then Valvoline rep told me they don't always list all the specs on the bottle label, which is lame, IMO.

They also misspelled "Porsche." Really?

It's not listed on any of the labels. Most appear to have been blended in June of 2019. Porsche is spelled correctly though...
