What is the best way to improve the fuel efficiency of my Toyota Corolla?

I recently purchased a Toyota Corolla and I am wondering what steps I can take to improve its fuel efficiency. I have read about different fuel additives, but I'm not sure if they actually work. I want to save money on gas and help the environment, so any advice would be greatly appreciated!

The best way to improve the fuel efficiency of your Toyota Corolla is by ensuring that your tires are properly inflated. Underinflated tires can decrease your gas mileage by up to 3%. Also, make sure to keep up with regular maintenance and tune-ups to keep your vehicle running efficiently.

Using fuel additives may have a small impact on your fuel efficiency, but the best way to improve it is by changing your driving habits. Avoid aggressive driving and excessive idling, and try to maintain a constant speed while on the highway. This can greatly improve your gas mileage.

Consider carpooling or using public transportation whenever possible. This not only helps reduce your carbon footprint, but also saves you money on gas. Plus, it's a great way to meet new people and make your commute more enjoyable.
