The SA from MotorImage told me 95 RON was the recommended fuel for their turbocharged Subaru units, the new Legacy GT included. Maybe it will run on 93, but prolonged use of below 95 may result in engine knock. Personally, I don't think it's worth the risk to save a few bucks at the pump. I think it best to use 95 as per recommendation, especially if that's what's listed in the owner's manual, though in a dire emergency I'm sure lower octane can be used (like if you need to refuel in the middle of nowhere and can't find a decent gas station) without much trouble as long as you don't make dire emergencies a habit.
