How to improve gas mileage in my Toyota Corolla?

I recently bought a Toyota Corolla and I'm concerned about the gas mileage. Is there anything I can do to improve it?

Regular maintenance is key in improving gas mileage. Make sure you get your oil changed, your tires properly inflated, and your air filter replaced when necessary.

Limit abrupt starts and stops while driving. This will help conserve fuel and improve your gas mileage.

Avoid unnecessary idling. If you're going to be stopped for more than a minute, turn off your engine to save gas.
