What ratio of additives should be added to improve the fuel efficiency of an Audi 80?

I have recently purchased a vintage Audi 80 and have noticed that its fuel efficiency is not as good as I expected. I have heard of additives that can improve fuel efficiency, but I am unsure of what ratio to mix them in. Can anyone provide recommendations?

For optimal results, mix in one ounce of fuel additive per 10 gallons of fuel. This will not only improve your fuel efficiency, but also help to keep your engine clean and running smoothly.

I would recommend starting with a small amount, around 0.5 to 1 ounce per 10 gallons. If you see an improvement, you can gradually increase the ratio, but be careful not to overdo it as too much additive can actually harm your engine.

Based on my experience with Audi 80s, I have found that a 1:1000 ratio of additive to fuel works best. This equates to about one teaspoon of additive per 10 gallons of fuel.
