I doubt it. Shell's GTL production facilities are mostly in the Middle East. Most of Quaker State's products come from fracking sites (dead dinosaurs) in PA (originally), hence the company's name, and, now, TX and OK. Also, none of QS's online material even hints at GTL processing. Of course, except for the cost of production (GTL ain't cheap), it really doesn't matter -- GTL or crude initially, the chemistry has come a LONG way. Moreover, QS's Ultimate stuff has a boatload of Moly (in whatever form it may be).
What? Quaker State is no different from any other Shell product, many of which are now blended with the GTL bases from Pearl, regardless of where that blending takes place. Why would Quaker State's historical roots have any bearing on what bases are used to blend it when the parent is a global oil giant?
To address your posit however, this is an excerpt from the MSDS for Quaker State Ultimate Durability 5w-30, SN GF-5:
Yes, that's 70-90% GTL.
That same CAS # appears, alongside other "interchangeable low viscosity base oils" on the MSDS for many other QS lubes including Defy and Enhanced Durability.
The MSDS for the Ultimate Durability 10w-30 also shows 70-90% GTL.
