How can I maintain the optimal fuel efficiency of my Toyota Yaris?

I recently purchased a Toyota Yaris and want to make sure I am maximizing its fuel efficiency. What steps can I take to ensure that my Yaris is running at its most efficient?

To maintain optimal fuel efficiency in your Toyota Yaris, make sure to regularly change your oil and air filter. This will help keep your engine running smoothly and efficiently.

In addition, using the recommended grade of fuel and keeping your tires properly inflated can also help improve your Yaris' fuel efficiency.

I would also recommend avoiding sudden accelerations and maintaining a steady speed while driving to conserve fuel.
