The most controversial information in your source was this:
There's other data that shows that Turbo GDI engines have specific issues with fuel dilution of the oil, and excess soot loading that leads to timing chain wear (and elongation), not to mention LSPI, which it appears depending on the specific formulation, old oils may not combat LSPI as well as fresh oil.* A 2007 Ford study found 12,000 mile old oil actually lubricated better than fresh oil; it had 10-15% lower friction and an order of magnitude lower wear rates. They found samples changed at 3,000 miles and 12,000 miles had very similar compositions of tribochemical lubrication films (Gangopadhay et al, 2007). I unfortunately can't find the full paper; I'd really like to see more detail on this because it's completely counter-intuitive. I've heard this mentioned before in various oil threads, but this is the first time I've found an actual study about it.
