One common culprit of poor fuel economy in Audi 80s is a dirty air filter. Make sure to check and replace your air filter regularly to improve your car's fuel efficiency.

Have you checked your tire pressure recently? Under-inflated tires can cause your Audi 80 to use more fuel. Make sure to keep your tires properly inflated for better gas mileage.

Another potential cause of poor fuel economy could be a faulty oxygen sensor. It's best to take your car to a mechanic for a diagnostic test to determine if this is the issue.
