FUD

The whole concept of oil is that it's a ~20+ long carbon-hydrogen chain or cycle. There's no such thing as completely different chemistry.
(even synthetics and non synthetics only differ in purity. Their chemicals are the same ones.)

The difference between 0w40 and 5w40 TD is in additives
Such as :

Some association decides what they want in their oil, and you put it in, hand it to them, pay them (yearly), and you get a sticker.

That doesn't mean that there aren't 1000 different blends that would be as good or better.
