Blanket statements like that are quite dangerous. I would not be surprised if we see an engine in the near future that can run 13:1 on 87 octane gasoline. The advances in engine design and (especially!) engine management are helping automakers run higher compression with the same fuel. The aforementioned 14:1 gasoline car will probably only need 91 octane, so it is likely that a 13:1 using the same technology would only require 87.
