What is the best way to optimize fuel efficiency in an Audi 80?

I recently purchased an Audi 80 and I'm concerned about my fuel consumption. What are some tips or tricks to improve my fuel efficiency in this car?

First and foremost, make sure your tires are properly inflated. Under-inflated tires can cause your car to use more fuel than necessary. Also, try to avoid rapid acceleration and braking as this can also impact your fuel efficiency. Additionally, using premium fuel can potentially improve your gas mileage.

I have found that keeping a consistent speed while driving can greatly improve fuel efficiency. Try to avoid sudden changes in speed and use cruise control when possible. Also, keep your car well-maintained and make sure you are using the recommended oil and filter for your Audi 80.
