How do I change the engine oil in an Audi A6?

I just bought a used Audi A6 and I'm not sure how to change the engine oil. Can someone give me instructions on how to do it properly?

Changing the engine oil in an Audi A6 is a relatively simple task, but it's important to do it correctly to ensure your car runs smoothly.

First, make sure you have all the necessary tools and supplies including oil, oil filter, wrench, and a drain pan. Then, locate the oil drain plug under your car and open it using the wrench. Let the oil drain out completely. Afterwards, unscrew the old oil filter and replace it with a new one. Finally, refill the engine with new oil according to your car's specifications.
