How to properly maintain the engine oil in an Audi A6?

I have recently purchased an Audi A6 and I want to make sure I properly maintain the engine oil to ensure its longevity. What steps should I take to ensure I am correctly maintaining the engine oil?

First and foremost, make sure to regularly check your engine oil levels using the dipstick. It is recommended to do this every time you fill up your gas tank.

Always use the recommended oil type and brand for your Audi A6. This information can be found in your owner's manual.
