How can I optimize fuel efficiency on my Audi A6?

I have been noticing that my Audi A6's fuel consumption has been quite high. What steps can I take to optimize fuel efficiency on my car?

Regular maintenance is key to optimizing fuel efficiency on your Audi A6. Make sure to regularly check and replace spark plugs, air filters, and oil filters to ensure your engine is running smoothly.

Avoid excessive idling and aggressive driving, as they can significantly increase fuel consumption. Instead, try to maintain a steady speed and use cruise control when possible.

Inflate your tires to the recommended pressure level and make sure they are properly aligned. This can greatly improve fuel efficiency and also prolong the life of your tires.
