How to optimize fuel efficiency in my Audi A6?

My Audi A6 seems to be consuming a lot of fuel lately. Are there any specific tips or practices that I can follow to improve its fuel efficiency?

As a fellow Audi A6 owner, I understand the struggle of finding good fuel efficiency. One tip I can give you is to always make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by 0.2 percent for every 1 psi drop in pressure. So regularly check your tire pressure and maintain it at the recommended level stated in your owner's manual.

Besides tire pressure, another way to optimize fuel efficiency is to drive smoothly and avoid sudden accelerations and hard braking. This can save you up to 33% on fuel consumption according to AAA. So be mindful of your driving habits and try to maintain a steady speed whenever possible.
