As per the manual of the Forester SJ, the non-turbo Foresters (FB20 engine) have a recommended 0w20 viscosity with 5w30 as an alternative. I may have to check again, to be sure.

The dealership may have switched to a different supplier and the new supplier does not carry the 0w20 viscosity. As long as the viscosity is within the manufacturer's limits, that is just fine.

Nope. Honda would not be using their 0w20 for all their gas model lineup if the 20 weight oil is too thin for our climate. Ford's Ecoboost engines also have a recommended 5w20 viscosity but most local Ford dealerships do not offer such a viscosity. Ford casas use 5w30 oil instead.
