How to improve fuel efficiency in an Audi 80?

I have an Audi 80 and I noticed that it consumes a lot of fuel. What can I do to improve its fuel efficiency?

Firstly, make sure your tires are properly inflated. Under-inflated tires can increase fuel consumption. Also, regularly change your air filter. A clogged air filter can decrease fuel efficiency. Lastly, avoid sudden accelerations and maintain a steady speed while driving.

Try using a fuel additive to clean your engine and improve its fuel efficiency. Additionally, avoid carrying unnecessary weight in your car and properly maintain your Audi 80's engine.

Consider upgrading to a more fuel-efficient model of the Audi 80. You could also try using cruise control on longer trips and avoid idling for long periods of time.
