Octane is a rating of a fuels resistance to ignition and has absolutely no bearing on a fuels potential stored energy...... higher octane ratings will not make more power in an engine unless conditions exist that warrant the higher octane rating. And even then it is the modifications that make the higher octane necessary that are making more power and not the higher octane fuel.
However..... higher octane pump fuels usually have a better additive package than the lower grade cheaper fuels.
Good answer, 100% correct.
