How can I optimize fuel efficiency in my Kia Picanto?

I recently purchased a Kia Picanto and have noticed that the fuel consumption is higher than expected. What are some technical tips I can use to improve fuel efficiency in my car?

Make sure to regularly check and change your engine oil. This can greatly impact your fuel efficiency.

Inflate your tires to the recommended pressure. Under-inflated tires can cause higher fuel consumption.

Avoid accelerating quickly and maintain a steady speed while driving.
