How do I improve the fuel efficiency in my Audi 80?

I recently purchased an Audi 80 and I've noticed that it's consuming more fuel than expected. Are there any tips or tricks I can use to improve its fuel efficiency?

One way to improve fuel efficiency in your Audi 80 is to make sure your tires are properly inflated. Under-inflated tires can increase fuel consumption.

Another tip to improve fuel efficiency is to avoid idling or using the air conditioning unnecessarily. This can save you some fuel and money in the long run.
