How do I increase fuel efficiency in my Toyota Corolla?

I recently purchased a Toyota Corolla and I'm looking for ways to increase its fuel efficiency. Are there any specific maintenance practices I should follow or modifications I can make to achieve better gas mileage?

Perform regular oil changes and tune-ups to keep the engine running smoothly. Also, make sure your tires are properly inflated to improve gas mileage.

Consider using a fuel additive to help clean and lubricate your engine, which can improve its efficiency.

Try to avoid idling for long periods of time and minimize sudden accelerations and braking, as these can use up more gas.
