How do I improve the fuel efficiency on my Ford Puma?

I've noticed that my Ford Puma's fuel efficiency has been decreasing lately. Is there anything I can do to improve it?

One simple way to improve fuel efficiency is by properly inflating your tires. This ensures that your car is using the recommended amount of fuel for each mile traveled. Additionally, keeping up with regular maintenance such as oil changes and air filter replacement can also help improve fuel efficiency.

Consider changing your driving habits. Avoid unnecessary idling, use cruise control on the highway, and try not to accelerate or brake too harshly. This can also help improve your car's fuel efficiency.

Another option is to use fuel additives or cleaners to improve the performance of your car's fuel system. However, be sure to do some research and choose a reputable brand before making a purchase.
