How can I improve the fuel economy in my Ford Fiesta?

I just purchased a Ford Fiesta and I'm looking for ways to improve its fuel economy. I've heard about certain modifications and techniques that can help, but I'm not sure what actually works. Can someone give me some advice?

One of the best ways to improve fuel economy is to keep your tires properly inflated. This reduces rolling resistance and can save you a significant amount of gas.

Another tip is to avoid excessive idling. If you're stuck in traffic or waiting for someone, turn off your engine to save gas.

Regular maintenance, such as tune-ups and oil changes, can also improve your Ford Fiesta's fuel economy. Make sure to follow the recommended schedule.

Consider using a fuel additive that helps to clean and lubricate your engine. This can improve fuel efficiency and overall performance.
