Higher octane burns slower and cooler, actually reducing the power. Advancing the timing allows the gas to burn hotter and more compete, increasing power.
So the two usually cancel each other other out.
Also, there is usually no point in spending more money on higher octane to get more MPG... you'd be better off putting that extra money toward more 8x octane gas.
To avoid excessive wear and heat in the engine, it's best to use the recommended octane.

so you're saying I need to run 81 octane in my supercharged trucks because the 100 octane racing / 93 octane street fuel is worthless???

Higher octane does not burn cooler. It simply resist detonation under pressure,{as the diesel effect}, but when the spark plug makes it detonate, it creates the same BTU energy as lower octane fuels. But detonating under higher compression, makes better use of the gasses expanding when they burn.
