Good read and well written ... thanks for the link.
On page 2 however, it said: "Decreased oil film thickness can lead to increased boundary lubrication and wear".
Is that correct? I'm wondering if he meant to say "Decreased oil film thickness can lead toincreased decreased boundary lubrication and wear."
One thing I see potentially happening with newer DI cars using xW-16 and xW-8 is the oil getting dangerously thin if the engine dilutes the fuel a lot. People that neglect to do routine OCIs on schedule with these really thin oils are risking doing some engine damage/wear IMO.

Thinner oil moves most parts further to the left on the Stribeck curve, which means toward boundary lubrication and more wear.

At boundary, there is some ¨metal to metal¨ (mostly rubbing peaks) contact, wear being avoided by AW. So thinner, makes more of such contacts.

Back in the day, full hydrodynamic was called the "zero wear" area, so "increased boundary lubrication" results from decreasing the film thickness.
In this regime, the additives are there to "control" wear rather than eliminate it.

Yes, correct as intended, but not clearly phrased.
