The Prius is designed to run on regular unleaded fuel, and using premium fuel is generally not necessary and doesn’t offer improved fuel economy.
Low-quality fuel o r fuel additives may affect performance and reduce fuel efficiency.
Stick to high-quality fuel and avoid additives unless specified by the manufacturer.
