Higher octane fuels have a higher resistance to burning, lower octane fuels burn easier. All octane fuels are required to have detergents by law. Use what is recommended by your vehicle and stop wasting money. You will not get more power by using a higher octane fuel, unless your vehicle is tuned to use it or developed to use different octanes like Mazda's sky active turbos.
It's also not necessary to use high octane fuel if the manufacturer recommends it. Modern cars have sensors and computers that adjust how it runs if you fill it with cheap gas so it doesn't knock or anything.
Running on a bad tune is not the same as running economically, octane sensors just determine the amount of tune modification needed to stay as economical as possible.
If you run a tank of the correct fuel and watch your st/lt trims then do the same with improper gas you'll notice they're not at all the same numbers.
