How can I improve my gas mileage in my Toyota Corolla?

I recently purchased a Toyota Corolla and I've noticed my gas mileage isn't as good as I expected. What can I do to improve it and save some money on gas?

First, make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage. Also, avoid carrying unnecessary weight in your car.

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

Consider using a fuel additive or switching to a higher quality gasoline to see if that improves your gas mileage.
