How to improve the fuel efficiency of my Kia Rio?

I have noticed that my Kia Rio's fuel efficiency has been decreasing recently. What can I do to improve it?

One way to improve your Kia Rio's fuel efficiency is to regularly check and replace dirty air filters. This will ensure proper air flow and increase your mileage.

Another tip is to avoid aggressive driving and excessive idling. These habits can significantly decrease your fuel efficiency.

Make sure to keep your tires properly inflated. Under-inflated tires can increase drag and decrease your mileage.
