What are some of the best ways to improve my Toyota Camry's fuel efficiency?

I recently purchased a Toyota Camry and I noticed that it's not as fuel efficient as I expected. Are there any specific maintenance tips or modifications I can make to improve its fuel economy?

Regularly check and replace your air filter to improve air flow and engine performance.

Try using a fuel cleaner every few thousand miles to remove any buildup in the fuel system that could affect efficiency.

Properly inflate your tires to the recommended pressure as this can greatly impact fuel efficiency.
