> uses the 92 octane fuel
There's no evidence that higher octane fuel is required or leads to performance gains in excess of the cost bump.

Knock (pre-ignition) will destroy an engine. I have a naturally aspirated infinity, but with compression ratio around 13:1 it calls for premium.
Believe me I wouldn't pay for it if it wasn't necessary. It's still cheaper than a new engine.
That being said, unless you are constantly flooring the accelerator and / or doing a lot of track driving, it seems challenging to make a modern (and properly functioning) engine knock on a persistent basis (irrespective of octane).
That's why higher compression engines REQUIRE higher octane fuel, as the manufacturer will specify. Run without it, damage your engine and try to make a warranty claim. Good luck with that!
Adding octane to fuel isn't adding a booster. It's adding stability to the fuel so it can be run in a higher compression engine. If your engine doesn't reach that pressure then you'll notice no effect except your wallet getting lighter.
