I think they use thicker and/or higher hths oil!
On the contrary - GM brands here issued a service bulletin a while back requiring certain gasoline-engined cars to use dexos1g2 to mitigate LSPI. This was slightly inconvenient as most oils here were dexos2, with few d1g2 options available.
VERY interesting info...thank you!
I have been guessing that we haven't heard much about problems with DIT engines using A3/B4 oils because of the higher ZDDP levels, as that additive is a strong LSPI quencher...but that it is only a guess.

Eliminating LSPI is an interesting part of this question. Lubrizol has been out in the market talking about LSPI protection on used oil (both the tests only
look at LSPI protection on new oil).
Lubrizol Podcast on LSPI
The updated -B1 Ford oil specs also include an LSPI test in a 2.0l EcoBoost, but I don't know how that test compares to the SN+ one.
