Why does my Ford EcoSport have low fuel efficiency?

I have been driving my Ford EcoSport for a few months now and I can't help but notice that its fuel efficiency has been decreasing. What could be causing this and how can I improve it?

One of the most common causes of low fuel efficiency in Ford EcoSport is driving with underinflated tires. Make sure to regularly check and maintain the proper tire pressure for better mileage.

Another culprit could be a dirty air filter. A clogged air filter can restrict airflow to the engine, making it work harder and use more fuel. Replace your air filter every 12,000-15,000 miles to improve fuel efficiency.
