I understand the benefits of oxygenation as well as energy density. However, it is not uncommon for modern high performance moderate-high compression motors (like ours) to have small amounts of detonation with 91 octane gas, especially when the motor is hot and/or the air is hot and dry. Likewise, they can adjust the timing to can take advantage of moderately higher octane fuel (94-96) when conditions warrant - like being on a dyno or on a race track.
Edit - sorry - missed the second page. RCZ is exactly right.
