How do I improve the fuel efficiency of my Ford Focus?

I've noticed that my Ford Focus isn't getting as many miles per gallon as it used to. Is there anything I can do to improve its fuel efficiency?

One easy way to increase your car's fuel efficiency is to make sure your tires are properly inflated. This can make a big difference in your gas mileage.

Regular maintenance is key to maintaining good fuel efficiency. Make sure to get your oil changed and have your car tuned up regularly.

Try to avoid idling for long periods of time, as this can waste a lot of gas. If you do get stuck in traffic, turn off your engine to save fuel.

Another way to improve fuel efficiency is to avoid carrying extra weight in your car, such as heavy luggage or unnecessary items.
