How can I keep my Kia Stonic's fuel efficiency at its best?

I recently purchased a Kia Stonic and I want to make sure I am keeping its fuel efficiency at its top performance. What maintenance tips and driving techniques should I follow?

Firstly, make sure to regularly check and replace your air filter. A clogged air filter can greatly decrease fuel efficiency.

Avoid aggressive driving, including speeding, quick accelerations, and sudden braking. This can waste a significant amount of fuel.

Keep your tires properly inflated. Underinflated tires can decrease fuel efficiency by up to 3%.

Use cruise control when possible. It helps maintain a steady speed, which can save fuel.
