I've got a 2009 legacy with the non-turbo 2.5l engine. I live upstate in NY, so it gets pretty cold here (-10F or sometimes lower). I usually use M1 5-30 in the Suby, but have been tempted to try Shell Rotella T6 (5-40) because of the lower price. Would that be acceptable over the winter ? Is there a better suggestion ?
