Do you honestly believe that, Merk? Look at the VOAs on PYB, QS, and FS. Within measurement tolerance, the additive packages are identical, and I'd be convinced that they were the same product in three different bottles unless I didn't believe Johnny, who told us they are, indeed, different products. Nonetheless, they all meet the exact same specifications and are functionally equivalent.
This does highlight the issue, though. Shell bought a bunch of brands specifically because of the brand name, only to let their own brand's reputation slip.
