Sorry but you're living in the land of dillusion...using octane higher then 87 for your Yaris will give you WORSE milage....why is this so hard for you to understand? Using higher octane means the combustion is RETARDED, meaning that it takes MORE gas to give the car the same power....this means lower milage...the only exception to this is if the car is engineered (tuned) for higher octane....you keep thinking that ALL cars behave the same with higher octane...this is dillusion, or worse.
