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

I just purchased a Toyota Camry and I'm looking for ways to increase its fuel efficiency. Any tips or suggestions would be greatly appreciated.

Regularly maintaining your car, such as changing the oil and air filter, can significantly improve fuel efficiency.

Driving at a consistent speed and avoiding unnecessary accelerations and decelerations can also help with fuel efficiency.

Consider using a fuel injector cleaner to optimize the performance of your car's fuel system.
