Oils are a total nightmare and its almost pointless having a discussion on them.
People are more divided on them than American politics. Its really hard to get the right recommendations and some of the auto shops where you put in your vehicle type don't help either with incorrect advice.
Best to go directly to the oil suppliers website and put in your manufacturer like I did with Mobil.

Hyundai recommends Shell oils but they are not really "Mainstream" over here in terms of availability or else I would go down that route.
I also refuse to use a 0-20W oil in our climate and in a turbo vehicle but lets not talk about that.
