I'd just like to point out that 93 octane is not available in several states, you are insinuating that Toyota is selling a car with an engine that damages itself if owned and operated in certain locations of the country.
The manual specifically states that 91 octane is perfectly acceptable for the vehicle and will cause no damage.
