Fuel Economy - Toyota Yaris Forums

In Toronto we get 87 octane as standard, 89 and 91 as premiums, and only one gas station offers more than 91, which is Sunoco. They offer "ultra94" which, as you can probably tell, 94 octane. Has anyone ever tried those octane boosters in the yaris? I've seen some from NOS that say they make any pump gas into 113 octane race fuel. Does that stuff really work? what would it do to our engines if used?
