How can I make my Audi A4 more fuel efficient?

I recently bought a used Audi A4 and I love it, but I noticed that it's not as fuel efficient as I expected. What can I do to improve its gas mileage?

One way to improve the gas mileage of your Audi A4 is to make sure you keep up with regular maintenance. This includes keeping your tires properly inflated, replacing air filters, and getting timely oil changes. These may seem like small things, but they can make a big difference in your car's fuel efficiency.

Another tip is to avoid aggressive driving and excessive speeding. These habits not only put you and others at risk on the road, but they also use up more fuel. Maintaining a steady speed and avoiding hard accelerations and sudden braking can help improve your Audi A4's gas mileage.

Consider using a fuel injector cleaner once in a while to keep your engine running smoothly and efficiently. You can also try adding a fuel additive specifically designed for improving gas mileage. Just be sure to follow the instructions carefully.
