Only known LSPI issue in Euro engines was first generation 1.4 turbo/compressor engine in VW. But VW resolved that quickly.
However, you have to take into consideration that European manufacturers are way ahead in so called "downsizing" game than American or Asian companies.
Also, 2.0 ltr engines are not as prone to LSPI. LSPI is primarily problem in engines 1.6ltr and lower displacement. 2.oltr engine in 2020 that has LSPI issue is poor engineering, there is no way around that. Personally, your choice of oil is good as Mobil1 0W40 FS is almost 0W30 oil. It is very light W40 oil.
I think you're on to something. In the ford community LSPI is almost unspoken of, though it is feared. For example on the focus St forums it's the bogeyman but the common factor for blown engines is aftermarket tunes. If I remember correctly, GM developed their Dexos tests due to the 1.6L ecotec blowing up. The Ecoboost is better platform in that regard. Heck, Ford specs semi-synth in-house Motorcraft for their EcoBoosts
Both Ford and GM have some know-how from their European brands. So, both have more experience with turbo applications than Asian manufacturers where LSPI is common in some brands. Also, Focus ST issue is not LSPI, it is open deck architecture of an engine. That architecture is really not good for such hp per 1ltr of displacement. BMW for example never wanted to bump radically hp in its 3.0 ltr engines as they are open deck. When they developed S55 engine for M3/4 F30 generation, they went back and changed the block. New BMW B generation engines are closed deck bcs. they are modular, and they will have versions running 500+hp from factory. So, Focus ST issue is actually much bigger than LSPI.
