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