How to increase mileage in a Ford Focus?

I have a 2011 Ford Focus and I am looking for tips on how to increase its mileage. I have tried regular maintenance and proper driving habits but I feel like there is more that I can do. Any suggestions?

One way to increase fuel efficiency in a Ford Focus is to regularly check and replace the air filter. A dirty air filter can significantly reduce gas mileage.

Another helpful tip is to avoid idling your car for extended periods of time. This can waste fuel and decrease your mileage.

Keeping your tires properly inflated can also improve your Focus' mileage. Check the recommended PSI and make sure your tires are at that level.
