You don't know the terminology. Group III+ doesn't mean Group IV (PAO). It means better Group III base stocks, primarily characterized by their higher viscosity index (VI) than for lower-quality Group III base stocks.
You're both right, and are just not wording it very elegantly. Group III+ isn't anything official, just something made up by oil companies to differentiate a certain product over "ordinary" Group III offerings. On one hand, there are some pretty find products called Group III+. On the other hand, every major oil company out there (and some not so major) has Group III products they differentiate from everyone else's. Chevron and their ISOSYN or whatever it is, Shell and PurePlus, Mobil and Visom, Petro-Canada and PURITY base oils....
