What type of oil should I use for an Audi 80?

I recently purchased a used Audi 80 and am unsure of the type of oil I should use for regular maintenance. I want to ensure the best performance and longevity for my beloved car.

For your Audi 80, it is recommended to use a premium quality synthetic oil with a viscosity of 5W-40. This will provide excellent protection for the engine and improve fuel efficiency.

To ensure proper lubrication and to prevent sludge build-up, it is best to steer clear of conventional oils and opt for a fully synthetic oil like Mobil 1 or Castrol. It may cost a bit more, but it will protect your engine in the long run.
