What can be done to improve fuel efficiency in a Kia Rio?

I've noticed that my Kia Rio's fuel efficiency isn't as good as it used to be. What can I do to improve it?

First, make sure your tires are properly inflated. This can greatly affect your fuel efficiency.

Consider using a fuel additive or fuel injector cleaner to help clean out any buildup in your engine.

Practice eco-driving techniques, such as accelerating gradually and avoiding sudden braking.

Regularly change your air filter to ensure proper air flow to your engine.
