How to optimize the fuel efficiency of a Ford Focus?

I have recently purchased a Ford Focus and I am looking for ways to improve its fuel efficiency. Any recommendations on driving techniques or maintenance tips that can help me save money on gas? Thanks!

One easy way to optimize fuel efficiency in your Ford Focus is to regularly check and replace your air filter. A clogged air filter can reduce gas mileage by up to 10%.

Properly inflating your tires can also improve fuel efficiency. Check your vehicle's manual for the recommended tire pressure and make sure to check it regularly.

Another tip is to avoid idling for extended periods of time. If you're going to be stopped for more than 30 seconds, turn off the engine.
