How to improve fuel efficiency on a Ford Focus?

I just purchased a Ford Focus and I have been noticing that the fuel efficiency is not as good as I expected. Is there anything I can do to improve it?

One easy way to improve fuel efficiency on a Ford Focus is to ensure your tires are properly inflated. Underinflated tires can decrease fuel economy by up to 3%. Also, try driving at a consistent speed and avoid sudden stops and starts.

Another helpful tip is to remove any unnecessary weight from your car. The heavier your car, the more fuel it will need to move. Take out any items that you don't need for your daily commute.

Regularly changing your air filter can also improve fuel efficiency by up to 10%. It's a simple and inexpensive maintenance task that can make a big difference.
