There is typically no discernable difference. The only thing a syn oil does is enable the user to extend change intervals.
This may or may not be a benefit for a particular user.
Using synthetic oils does not result in magic longer engine life.
There are too many other influencing factors.
Wrong
Syns keep TGDI/GDI engines cleaner and are beneficial when extreme low temps and extreme high temps occur, both outside the engine and inside the engine.
If manufacturers already broke the engine-in - prior to product retail sale, the factory oil would be full syn.
It's always been a good rule-of-thumb from many BITOGERs here and many vehicle mechanics online, to allow 3K after new vehicle purchase, before running full synthetic oils.
That's when the added benefit of having full syn starts paying better dividends. Keep your factory-fill in for a while. Odds are, it's conventional or semi-syn and good for the new engine break-in.
If your new vehicle comes with full syn, then that's a sign the manufacturer trusts the new engine already has the right digital parts-specs for that engine and either none or very little additional break-in period is needed.
There is little fact in what you have posted.
