How to maximize fuel efficiency in an Audi A6?

I recently bought an Audi A6 and I've been noticing that I'm not getting as many miles per gallon as I expected. What are some tips and tricks to increase fuel efficiency in my car?

Regularly maintain and service your car in accordance with the manufacturer's recommendations. A well-maintained engine will run more efficiently and use less fuel.

Avoid aggressive driving, including frequent accelerating and braking, as this can greatly impact your fuel efficiency. Try to maintain a steady speed and anticipate traffic.

Check your tire pressure regularly and ensure they are properly inflated. Underinflated tires can decrease fuel efficiency by up to 3%. Also, consider switching to fuel-efficient tires.
