What is the best way to improve gas mileage in the Audi A6?

I recently purchased a new Audi A6 and the gas consumption seems to be higher than expected. I want to know what steps I can take to improve the gas mileage and reduce my fuel expenses.

Regular maintenance is key to improving gas mileage in your Audi A6. Keeping your car's filters clean and ensuring the tires are properly inflated can make a big difference.

Consider using a fuel additive to improve the efficiency of your Audi A6's engine. These additives can help clean and lubricate fuel injectors, increasing your car's gas mileage.
