Tom, you'll find your subaru has a significant amount of carbon build up in the cylenders. That increases the compression ratio and requires higher octane, slower burning fuel. I'd recommendcleaning the injectors if njected and or running a few cans of additive such as BG 44k. Either should do a fairly good job of removing the carbon. Water does a fantastic job as well, but is risky. Have to drop exhaust system, as it'll damage convertor and trickle through at high rpm to prevent hydro-locking engine and related massive internal damage! There's also a small possibility the knock sensor, map/barometric sensor are not functioning as intended too.hotshoetom said:My subaru manual says 87 octane, but it rattles like castanets on anything less than 89 octane. The bike doesnt rattle or at least I cant hear it if it does...wind noise being a major offender. So whether it was designed for 87 or not isnt really the question...did this bike come with a slightly higher octane requirement??? We'll find out after a few tanks of the middle grade. If there isnt any change then I will go back to 87 and will just shut up about all this.
