How can I improve the gas mileage in my Ford Focus?

I just bought a Ford Focus and I want to save money on gas. Are there any specific driving techniques or modifications I can make to improve the gas mileage?

One way to improve your Ford Focus' gas mileage is to avoid aggressive driving. Accelerating and braking quickly can decrease fuel efficiency.

Another tip is to keep your tires properly inflated. Under-inflated tires can decrease gas mileage.

Regular maintenance such as oil changes and air filter replacements can also improve gas mileage.
