Prius is a hybrid petrol vehicle, not an external-charge EV unless it is Prius Prime/PHEV. Regular unleaded 91 RON or higher accepted.
What happens if I use a lower octane fuel?
Do not use a grade below the stated minimum. A higher number is not automatically better unless the manufacturer says so.
