How to properly change the engine oil in an Audi 80?

I have recently purchased a used Audi 80 and I want to know the correct procedure for changing the engine oil. Can someone provide me with step-by-step instructions and any necessary tools that I will need?

First, you will need to gather the necessary tools and materials such as a oil filter wrench, oil filter, and sufficient amount of engine oil. Make sure to refer to your vehicle manual for the recommended type and amount of oil. Begin by locating the oil filter and drain plug under the vehicle and use the oil filter wrench to remove the old oil filter. Next, drain the old oil by removing the drain plug and allowing it to drain completely. Once drained, replace the drain plug and install the new oil filter. Finally, fill the engine with the recommended amount of new oil and dispose of the old oil properly.
