How to improve the fuel efficiency of a Kia Picanto?

I just bought a Kia Picanto and I noticed that it's not as fuel efficient as advertised. Is there any way to improve its fuel efficiency?

Firstly, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.

Also, avoid unnecessary idling. If you're stuck in traffic or waiting for someone, turn off your engine to save fuel.

Additionally, try to avoid carrying excess weight in your car. The more weight your car carries, the more fuel it will consume.

Lastly, maintain your car regularly. A well-maintained car will have better fuel efficiency. Get your oil changed, air filter checked, and overall maintenance done according to the manufacturer's recommendations.
