How to get the best fuel efficiency in a Volkswagen Passat?

I recently purchased a Volkswagen Passat and I want to make sure I am getting the best fuel efficiency possible. What are some tips and tricks to improve the fuel efficiency in this vehicle?

Maintain proper tire pressure - this can greatly increase fuel efficiency. Also, try to drive at a consistent speed rather than constantly accelerating and braking.

Consider using premium gasoline instead of regular - it may be more expensive but it can lead to better fuel efficiency.

Make sure to keep up with regular maintenance such as oil changes and air filter replacements - this can greatly impact your vehicle's fuel efficiency.
