Talk about hi-jacking a thread.....

The OP's question concerned using hogh octane for better fuel mileage, and
you've morphed it into discussing better performance.

I think that the message that I was trying to get across was that water
injection effectively raises the octane level and performance of an
engine.  The wikipedia link was talking about the same thing.

Water cannot increase the octane level but it can make the engine
perform like a higher octane fuel is present by slowing the explosion
down so more thrust can be harnessed with less cylinder head damage.

Water injection reduces the octane requirement of the engine by
cooling the combustion chamber. This is partly due to the latent heat
of vaporization of water. The water "sucks up" some of the heat that
would otherwize work on the end-gasses.

Better performance GENERALLY also translates to better fuel mileage if
you do not use the extra power available.
