Nope. Running more octane than you need is a waste - it's actually slightly less efficient (unless, as stated, your engine is running hot/pinging/detonating when it shouldn't be). Octane is introduced as a chemical, and 92 will have more of it, and it will actually retard the burn in addition to displacing some of the gasoline. That means slightly lower energy content. That's why, unless the engine needs it, it's a double waste to run extra octane.



Absolutely and well stated!!
