There is no such thing as an "octane" rating of over 100. Over 100 it
is an "aki" or antiknock index..

Antiknock Index and Octane Rating are the same thing. You're
trying to sound intelligent there, but you're shooting
yourself in the foot...

Then why is ethanol added to regular gas at 10% and not added to
premium (in very many cases)???

It usually is added to premium in the US. I don't know
why Canada is different, but I suspect it's due to tax
policy.

In the US, ethanol is used because:

a) it's an effective octane booster
b) it's cheap compared to the alternatives
c) the energy act of 2007 provides Federal incentives
d) it does not have the legal liabilities of MBTE

e) intense pressure exerted by the Corn Ethanol Lobby
