Interesting comment in one of the links;
Industrial customers put value on performance.
Consumers put value on the word synthetic.
My favorite is that GTL base lubes will available up to 9 cSt.
I now wonder if German Castrol will be available in 15W50 soon, for about the same price as GTX?
I suppose some people will still be pushing PAO engine oil blends five or six years from now.
And some people will still spend 4X the money for them for no real or imagined performance edge.
But, at least they will have the warm fuzzy feeling gained from using a real synthetic.
