What scientific reasons?
Conjecture is more like it.
There are no studies offered to back up the claims made in the post.

Such real-world tests, unless done with the proper controls and done
with several trials would be anecdotes. The plural of anecdotes is not
data.
The best advice would be to follow the break-in procedures recommended
by the vehicle manufacturer, the people who know the engines the best,
and the people who employ people with real expertise.
