What is the best fuel for a Toyota Prius?

I just bought a Toyota Prius and I'm not sure what type of fuel I should be using. I've heard some people say that using premium fuel will improve the performance, but I've also heard that regular fuel is fine. What do you recommend?

Using premium fuel in a Toyota Prius is not necessary and will not improve the performance. The engine is designed to run efficiently on regular fuel. Save yourself some money and stick with regular fuel.

I've been using regular fuel in my own Toyota Prius for years and have never experienced any issues with performance. Stick with what the manufacturer recommends.

Some people believe that premium fuel is better for the engine, but in reality it won't make much of a difference. Stick with regular fuel to save money and reduce emissions.
