Lower octane fuels have no advantages other than being cheaper. Higher octane fuel simply makes it possible to run more advanced ignition timing, and therefore allows you to get more performance out of an engine, but you won't notice a difference in fuel consumption unless your car's software has been customised or you have a Carburetor specifically adjusted for higher octane fuels.
