How do I optimize the fuel efficiency in my Kia ProCeed?

I have noticed that my Kia ProCeed's fuel efficiency has been decreasing recently. What are some ways I can improve it?

Make sure your tires are properly inflated. This can greatly impact your fuel efficiency.

Avoid aggressive driving and sudden stops. This can waste fuel and decrease efficiency.

Regularly maintain your engine and replace old air filters. A well-maintained engine can greatly improve fuel efficiency.

Consider lighter driving, such as using cruise control on the highway, and try to avoid idling for long periods of time.
