Well said.
Octane is a measure of knock resistance, nothing else.
Higher octane fuel is not any more powerful. It may permit an engine to generate more power if it is engineered for it.
Higher octane fuel burns slower (to reduce the likelyhood of knocking).
If you don't need it, there is no reason to pay extra for it.
There is more that can be said about the difference in fuel that is labeled regular and that is labeled premium, but you still really end up with DemonSVT's comments.
