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

I recently purchased a Ford Focus and I am looking to improve its gas mileage. I heard that there are certain tips and tricks that can help. Can anyone provide some advice?

One easy way to improve gas mileage on any vehicle is to make sure your tires are properly inflated. Under-inflated tires can lead to decreased fuel efficiency.

Another tip is to lighten the load in your car. Excess weight can cause your car to use more fuel, so make sure to remove any unnecessary items from your car.

Avoid aggressive driving, such as rapid acceleration and hard braking. This can greatly decrease gas mileage.

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