How can I increase my Toyota Prius's fuel efficiency?

I have noticed that my Toyota Prius's fuel efficiency has decreased recently. What steps can I take to improve it? Is there a specific maintenance routine I should follow?

Regularly checking and changing your air filter can greatly improve your Toyota Prius's fuel efficiency. Also, make sure to follow the recommended maintenance schedule for your vehicle.

Another way to improve your Prius's fuel efficiency is by regularly checking and maintaining your tires. Properly inflated tires can reduce fuel consumption.

Consider investing in a hybrid-specific maintenance service for your Prius, which can optimize its performance and fuel efficiency. However, keep in mind that this service may be more expensive than a regular maintenance service.
