What is the best way to improve the fuel economy on an Audi 80?

I recently purchased an Audi 80 and I am concerned about its fuel efficiency. What are some ways I can improve the fuel economy on my Audi 80?

One way to improve your Audi 80's fuel economy is by ensuring that your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%. Make sure to check your tire pressure regularly.

Another tip is to avoid aggressive driving and excessive idling. Both of these can waste fuel and decrease your Audi 80's fuel efficiency. Try to maintain a consistent speed and avoid unnecessary idling.

You can also consider using a fuel additive to improve your Audi 80's fuel economy. Look for additives that are specifically designed for your car's engine and follow the manufacturer's instructions.
