I would also ask why ? .... I did a tankful of 91 Octane recently (just to see if I would get better mileage) and there was neither any real difference in performance or fuel economy. You are just throwing your money away .. when you drive a Yaris, as the vehicle doesn't take advantage of the higher octane gasoline.
