Which oil should I use for my 1991 Audi 80?

I'm planning to do an oil change on my 1991 Audi 80 and I'm not sure which oil is the best fit for my car. I'm looking for something that will improve performance and increase the longevity of my engine.

For your 1991 Audi 80, the best oil to use would be a high mileage synthetic oil. This will provide better protection and help clean any build up in your engine. From personal experience, I would recommend the Mobil 1 High Mileage oil.

If you're looking for improved performance and longevity, a full synthetic oil would be the best option for your Audi 80. I've had great results with the Pennzoil Platinum High Mileage oil.

To maintain the condition of your engine, it is important to choose an oil with the right viscosity and additives. I would recommend using the Castrol EDGE High Mileage oil for your 1991 Audi 80.
