How to maintain my Kia Picanto's fuel efficiency?

After driving my Kia Picanto for a few months, I've noticed that the fuel efficiency has decreased. How can I maintain it to get the best mileage possible on my daily commutes?

Regularly check your tire pressure and keep it at the recommended level. Underinflated tires can decrease fuel efficiency.

Avoid aggressive driving and sudden accelerations. This can burn more fuel than necessary.

Make sure your engine is regularly serviced and tuned up. A well-maintained engine can improve fuel efficiency.
