Unless the engine is tuned for a higher octane fuel you are wasting your money as the slower burn rate will decrease the HP.
However what it is good for is stopping pre ignition that can soon ruin an engine so whatever you choose to use won't do any harm as IMHO they all do the same thing, so one isn't any better than another regardless of price.
