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.

Can high octane fuel damage an engine?
The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. 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 add horsepower?
