I'd like to see some proof that this has any advantages at all. While it
may not cost much, IMHO it's just a waste of money and resources.

The point is, you are getting rid of impurities that otherwise have to be
filtered. If the oil still look clean, I will agree that there is little
point, but those cases are rare.

For it to be of any real benefit - and I dispute this - it would have to
be from when the vehicle is new, and how many keep a new car until it's
worn out?


Well, replacing a car just because it's X number of years old is what I call
a waste of money and resources !.. :~)
