The 10w40 Motul is fine for winter driving, but I would be getting a heavier (higher viscosity) oil for summer driving i.e. a 15w40 or 15w50 for a bit of extra protection.
Depends on how warm and fuzzy you would like to feel.

Don't know if its bullshit or not but i have been told that running oil in a subaru that is higher in viscosity than from what the factory recomends can mess around with the knock sensor ???
