How do I improve the fuel efficiency on my Kia Stonic?

I've noticed that my Kia Stonic's fuel efficiency has decreased over time. What steps can I take to improve it?

Regularly maintain your car by getting oil changes, replacing air filters, and checking tire pressure. This can greatly improve fuel efficiency.

Avoid aggressive driving and excessive idling. These habits not only waste fuel, but also put unnecessary strain on your car's engine.

Consider using a fuel stabilizer or fuel injector cleaner to keep your engine running smoothly and maintain fuel efficiency.
