If that was the case, we also wouldn’t have crappy OE tires from the factory. The whole “if it was good, they’d do it stock” argument is a fairly bad and disingenuous because no, they won’t always do things or put things on that are good or better.Tell that to the members who posted pics of the goo. If it were so good companies like XOM, Pennzoil, HPL, and Amsoil, to name a few would be using it. They're not.
