How do I replace the engine oil in my Audi 80?

I recently noticed that my Audi 80 is due for an oil change. What steps should I follow to replace the engine oil correctly and safely?

First, gather the necessary tools and materials, including new engine oil, an oil filter, and a drain pan. Next, locate the oil drain plug on the bottom of the engine and unscrew it using a wrench. Allow the old oil to drain completely before replacing the oil filter and filling the engine with new oil according to your owner's manual.

To ensure no mess, place a large piece of cardboard or an oil drip pan under the car before starting the process. As a precaution, wear gloves and protective eyewear while handling the oil and engine parts.

Properly dispose of the old oil by taking it to a recycling center or an automotive shop that offers oil recycling services. Remember to always follow local regulations and guidelines for proper disposal.
