Is it necessary to change the engine oil regularly?

I recently purchased a used Audi 80 and I am not sure if I need to change the engine oil. How often should I change it and what are the consequences if I don't do it regularly?

Yes, it is absolutely necessary to change the engine oil regularly. It is recommended to do it every 5,000 miles or every 6 months, whichever comes first. Failing to do so can cause damage to the engine and decrease its lifespan.

Changing the engine oil regularly is essential for the proper functioning of your Audi 80. Not doing so can result in lower performance, increased fuel consumption, and potential engine failure. Make sure to follow the manufacturer's recommendations for oil change intervals.
