What is the best way to improve the gas mileage of a Ford Focus?

I have been driving my Ford Focus for a few months now and I have noticed that it doesn't get the best gas mileage. Are there any tips or tricks to help improve its fuel efficiency?

One way to improve the gas mileage of your Ford Focus is to make sure you are properly inflating your tires. Under-inflated tires can negatively affect fuel efficiency. Also, try to avoid excessive idling and use cruise control on long trips.

Another tip is to regularly maintain your car, including changing your air filter and oil at the recommended intervals. These simple tasks can help improve your Ford Focus' gas mileage.
