How to improve the Fuel Efficiency of Kia Soul?

I have been noticing that my new Kia Soul is not giving me the advertised fuel efficiency. Is there anything I can do to improve it?

Firstly, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%. Regularly check and maintain the recommended tire pressure.

Avoid aggressive driving. Fast acceleration and braking consume more fuel. Try to maintain a steady speed and use cruise control on long trips.

Keep your car well-maintained. Regularly changing the air filter, oil, and spark plugs can significantly improve fuel efficiency.
