If I mix 2 oz of water in with 10 oz of Coke...I'm technically getting 12 ozs in my glass but only 10 ozs of it is Coke. It's diluted. Same concept with gas. It gets diluted and you get less per gallon....

If high compression auto engines are anything like aircraft engines, a little gas in the fuel can cause pretty serious problems.

More basically than that, what I meant was that the octane rating of gas is a measure of it's ability to resist spontaneous combustion from heat and pressure. Nothing more, nothing less. Water won't dilute the gasoline or alter the octane rating in any way. What you're Toyota tech told you doesn't make any sense.
Water in a high compression ratio engine - and it doesn't get higher than an airplane engine - is bad because it doesn't compress. A small amount of water going into an engine like that could easily destroy it.
