You'd like to think that Subaru would have mapped UKDM exports on widely-available UK fuel i.e. 97 (possibly 95), wouldn't you?
But until you get an answer by someone that DEFINITELY knowsr, I seriously wouldn't play Russian roulette with det - stick in the best available i.e. V-Power nee Optimax!!! It's simply not worth you 'having lived to regret it', lol!
It will run on 95, but timing will be pulled and you won't be making advertised power/torque.
Yeah, but should there be the presence of serious det, will 95 very quickly cause the IAM to retard to 0, therefore now offering no further protection should the det get worse?
when I pulled the scoob and my old evo IV into my garage I could definately hear an engine knocking noise when running on 95. Filled them up with 99 and the noise went.

If the IAM reaches around 4-5(Rom dependant) boost control will be disabled, wastegate duty will be set at 0 and you'll know there is a problem. Quite unlikely to happen running a newage STi on 95 RON, I personally wouldn't run any less than 97, but Subaru know that people will possibly put lower grade fuels in and have safeguards built into the EMS.

Nice answer, cheers for adding to the ol' knowledge, lol
