What is the best way to improve the fuel efficiency of a Ford Fiesta?

I recently bought a Ford Fiesta and I'm looking for ways to improve its fuel efficiency. Are there any specific modifications or maintenance tips that can help me achieve better gas mileage?

As someone who has been driving a Ford Fiesta for years, I can offer some personal advice. Firstly, make sure to keep your tires properly inflated as underinflated tires can significantly reduce your fuel efficiency. Secondly, get a tune-up regularly to ensure your engine is running smoothly. And finally, try to avoid aggressive driving habits as they consume more fuel.

I am a Ford certified mechanic and I can tell you that changing your air filter can greatly improve your fuel efficiency. A clogged air filter restricts airflow to the engine and can reduce fuel economy by up to 10%. Also, make sure you are using the recommended grade of motor oil for your car.

Another thing you can do to improve fuel efficiency is to reduce weight in your car. Take out any unnecessary items from your trunk as the extra weight can decrease fuel economy. Also, keep up with regular maintenance and use fuel additives that are designed to improve gas mileage.
