How to improve fuel efficiency in the Ford Focus?

I recently bought a Ford Focus and I'm looking for ways to improve its fuel efficiency. Any tips or tricks?

The best way to improve your Ford Focus's fuel efficiency is to make sure you keep up with regular maintenance, such as oil changes and tire rotations. Also, driving with a light foot and avoiding excessive acceleration and braking can greatly improve your gas mileage.

Another tip is to keep your car's weight to a minimum. This means removing any unnecessary items from your trunk and making sure you don't overload your car with passengers or cargo.

You could also consider investing in more aerodynamic tires or adding a cold air intake to your engine, as these can also help improve fuel efficiency.
