5w40 is the recommended oil by Subaru UK too... though environmental conditions elsewhere in the world may not suit this oil. However, my local specialist (who are renowned and very well respected over here) recommend 10w50 which might help reduce oil consumption as it's a bit thicker and therefore shouldn't squeeze past piston rings etc as easily.
