Yes, exactly, Shell has a pretty narrow slate of GTL base oil viscosities, while Mobil's slate of PAO options is massive, and then there is mPAO on top of that.GTL and grp III come in a limited number of viscosities (all pretty low), while PAO can be made to pretty much any viscosity you like. So if you are making high viscosity stuff you are limited in the amount of GTL and GRP III you can use. And if you use it, the Noack will get worse
