How do I maintain a steady fuel efficiency in my Toyota Camry?

I recently bought a Toyota Camry and although it has good fuel efficiency, it seems to fluctuate a lot. Is there something I can do to maintain a consistent fuel efficiency?

Firstly, make sure to keep your tires inflated to the recommended pressure. This can greatly affect your fuel efficiency. Also, avoid aggressive driving and use cruise control on the highway to keep a steady speed. Lastly, regular maintenance such as oil changes and air filter replacements can help keep your fuel efficiency consistent.

In addition to the previous answer, you can also try using a fuel-efficient driving technique called hypermiling. This involves anticipating traffic and using coasting and gentle braking to conserve fuel. Additionally, you can invest in fuel additives or use premium fuel, which can help improve your fuel efficiency.

Another important factor is to reduce unnecessary weight in your car. Don't carry around heavy items in your trunk and try to clean out your car regularly. Additionally, avoid idling for long periods of time and plan your routes in advance to avoid unnecessary driving.
