This is an argument that has raged since the dawn of internet forums. Some say snake oil, some say their car will literally fall apart, flip upside-down and burst into flames unless they exclusively only put premium stuff in. For what it is worth here is my take.
More power? On many many track days in many many different cars I've never had any change in lap times due to filling up with a premium fuel. Big power tuned turbo cars respond well to premium fuels, in fact, my old VX220 turbo was mapped to run on a minimum of 97 ron to maximise the benefit of a higher octane.
More economy? If there is an improvement in MPG I've never noticed it. This is a concept that confuses the living death out of me, if there is a marginal financial gain then surely it counts for diddly squat any way. Premium fuel is expensive!
Cleaner engine? I can't vouch for other cars/engines but the M54 responds very well to a good thrashing once in a while. It would work out cheaper (and more fun) in the long run to do as Andy says, "red line a day keeps the carbon away" (that made me chuckle by the way).
For me, if I was chasing milliseconds on lap times I'd fill up with premium fuel, otherwise, the bog standard stuff will do me nicely. If buying premium fuel makes you feel a bit better about your car then why not continue with it. It certainly isn't doing any harm.
