One way to improve your Ford Focus's mileage is to make sure your tires are properly inflated. This can greatly affect your car's fuel efficiency.

You can also try using cruise control while driving on the highway. This can help maintain a consistent speed and improve your car's mileage.

Another tip is to remove any excess weight from your car. This can include removing unnecessary items from your trunk, which can decrease your car's fuel efficiency.
