How can I properly maintain the oil level in my Audi A4?

I've noticed that my Audi A4's engine oil level has been fluctuating and I want to make sure I am properly maintaining it. Can anyone provide some insights or tips on how to efficiently check and maintain the oil level in my car?

It is important to check your Audi A4's engine oil level regularly to ensure proper performance and longevity. You can do this by using the dipstick located under the hood of your car.

When checking your oil level, make sure your car is parked on a level surface and the engine is cool. Pull out the dipstick, wipe it clean, and then reinsert it to get an accurate reading.
