This gives me an idea. Octane booster could be held separately from low-octane fuel, and mixed as conditions dictate. The majority of the time that an engine operates, it doesn't require the full octane rating.

Colder air or higher elevations at light load would reduce the octane mixture. Heavier loads at lower elevations would increase the octane mixture.

Perhaps there would be cost and performance improvements by having continuously adjustable octane?
