What kind of oil should I use for my Audi 80 and how often should it be changed?

I'm unsure what type of oil is recommended for my Audi 80 and how frequently it should be changed. Can you please provide some guidance on this?

Only use fully synthetic oil in your Audi 80. It provides better engine protection and performance compared to conventional or synthetic blend oils. As for frequency, it is recommended to change your oil every 5,000 to 7,500 miles, depending on your driving habits and conditions.
