Of course, that's technically true. But, look at their answer to question 8, notably the last sentence:
"Pennzoil Platinum Full Synthetic products use 100% PurePlus Base Oils."
There is no such thing as a "+" base stock, but a "plus" base stock exists?
Check out the answer to question four under GTL/Testing. They state that the PurePlus base stock is Group III and reiterate that there is no API classification of Group III+ base stocks. PurePlus is Pennzoil's marketing term for their GTL base stock. Fancy names and slogans are par for the course in motor oil marketing, just like M1's "Advanced full synthetic", Castrol's "SPT" (Syntec Power Technology), Amsoil's "The First in Synthetics", and Kendall's "Liquid Titanium". When you see the TM mark, you know you are dealing with a trademarked name for a product rather than a description of its governing body specifications.
