Let me just add, the JDM wrx and sti run on 100+ ron fuel, but the af mixture is typically subaru extra rich, like 11.5 to 10.8 on high boost. Then add the knock sensor that will back off on the timing you should be reasonably safe from blowing your motor up in most cases ( mine is fine for now ). Now on the track I heard a few have access to jet fuel ( and if it is true want some! ) , add some of that to the tank to get higher octane, you will be fine with either.
Plus I haven't seen a Sti here blow up on our crap gas in daily driving. Yet ( who knows maybe it's jsut waiting to happen now lol )
