How to improve the fuel efficiency of my Kia Ceed?

I recently bought a Kia Ceed and I've noticed that it's not as fuel efficient as I expected. What steps can I take to improve its fuel efficiency?

First, make sure you are maintaining proper tire pressure. Under-inflated tires can decrease fuel efficiency.

Check your air filter regularly and replace if necessary. A clogged air filter can reduce fuel efficiency.

Try to avoid excessive idling and unnecessary acceleration. These habits can significantly impact your fuel consumption.
