How to improve the gas mileage of my Ford Puma?

I recently bought a Ford Puma and I noticed that its gas mileage is not as good as advertised. What can I do to improve it?

One way to improve gas mileage is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.

Regularly changing your air filter can also improve gas mileage.

Try to avoid aggressive driving habits like rapid acceleration and hard braking, as this can negatively impact fuel efficiency.
