How can I improve the fuel efficiency of my Audi 80's engine?

I love my Audi 80, but I feel like I'm constantly filling up on gas. Are there any steps I can take to improve its fuel efficiency?

First, make sure your tires are properly inflated as under-inflated tires can decrease fuel efficiency. Secondly, try to avoid aggressive driving and instead drive at a steady speed. Lastly, regularly maintain your engine by getting oil changes and replacing air filters. This can greatly improve your Audi 80's fuel efficiency.

Consider using cruise control when driving on long stretches of highway to maintain a consistent speed and save on gas. You can also try using premium fuel, which may be more expensive but can improve fuel efficiency in some vehicles.

One often overlooked factor in fuel efficiency is excess weight. Make sure to remove any unnecessary items from your Audi 80, especially if you frequently use the trunk for storage. Additionally, avoid idling for extended periods of time as it wastes fuel.
