How do I get better fuel efficiency in my Toyota Prius?

I bought a Toyota Prius for its fuel efficiency, but it doesn't seem to be as efficient as I expected. What can I do to improve its fuel efficiency?

Make sure you are using the recommended type of gas for your Prius. Using a lower octane fuel can decrease fuel efficiency.

Regularly maintain your Prius by getting tune-ups and oil changes, as well as using quality air filters. This can greatly improve fuel efficiency.

Avoid idling for long periods of time. If you anticipate being stopped for more than a minute, turn off the engine to save on fuel consumption.
