How can I improve the fuel efficiency of my Ford Puma?

I recently bought a used Ford Puma and I've noticed that it's not getting the best gas mileage. What are some tips and tricks I can try to improve its fuel efficiency?

One thing you can do is make sure that your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.

Try refraining from aggressive driving, such as quick accelerations and hard braking. This can also improve the fuel efficiency of your car.

Regular maintenance, such as oil changes and air filter replacements, can also make a big difference in your car's fuel efficiency.
