How do I maintain the fuel efficiency of my Kia Picanto?

My Kia Picanto used to have a great fuel efficiency, but lately I've noticed that it's consuming a lot more gas. How can I keep my Kia Picanto's fuel efficiency high?

One common cause for decreased fuel efficiency is a dirty air filter. Make sure to regularly check and clean or replace your air filter.

Overinflated tires can also result in decreased fuel efficiency. Make sure to regularly check the air pressure in your tires and keep them at the recommended level.

In addition to checking your air filter and tire pressure, regularly servicing your car and changing the oil can also help maintain fuel efficiency.
