What are some ways to improve the fuel efficiency of a Toyota Camry?

I recently purchased a Toyota Camry and I'm looking for ways to improve its fuel efficiency. Are there any modifications or driving techniques that can help decrease fuel consumption?

One of the easiest ways to improve fuel efficiency is to regularly maintain your car according to the manufacturer's recommendations.

Avoid unnecessary idling, as idling for just 10 seconds can use more fuel than restarting your car.

Consider investing in a fuel efficiency chip or tuning your engine to optimize its performance.
