How can I increase the fuel efficiency of my Kia Ceed?

I recently purchased a Kia Ceed and I noticed that I am spending more on fuel than I expected. Is there any way to improve the fuel efficiency of my car?

Making sure your tires are properly inflated and getting regular tune-ups can greatly improve your car's fuel efficiency.

Avoiding sudden accelerations and heavy braking can also help in reducing fuel consumption.

Regularly cleaning and replacing air filters can also improve your car's fuel efficiency.
