How to increase fuel efficiency in a Kia Stonic?

I recently purchased a Kia Stonic and I noticed that its fuel efficiency is not as great as I expected. Are there any tips or tricks that I can do to improve its fuel efficiency?

One thing you can do is regularly check and replace your air filter. A clogged air filter can decrease fuel efficiency, so make sure it's clean.

Avoid idling for too long. If you're going to be stopped for more than 30 seconds, it's better to turn off your engine to save fuel.

Try to avoid carrying unnecessary weight in your car. The heavier your car, the more fuel it will consume. So, declutter your trunk to improve fuel efficiency.
