It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
Does 93 octane burn faster?
These octane level numbers (87, 89, 91, etc.) Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock.
