I'd go with either of the Jaso oils. The Bardahl would be my first choice.
You don't necessarily have to go with a 20W-50 oil either. 15W-40, 15W-50 even 10W-40 would be fine. But for all choices if it's JASO rated that will be your best choice.
As to the SN rating. That covers any lower rating from SE - SL.
