The engine oil is designed to lubricate the internal components of your Audi A6 engine, but as it is used, the less lubricating it becomes, which can cause permanent wear to the inside components of your engine. Replacing the engine oil can be done at home, and with simple tools, you can end up saving some money, especially if you're used to paying the dealership. The computer in your A6 will even keep track of the oil life and warn you when it is time to change it. Gather the basic tools mentioned below, then read on to learn how to replace the engine oil and filter in your Audi A6.

Audi A6 C6: How to Change Oil

Materials Needed

  • Jack and jack stands
  • Drain pan
  • Socket
  • Engine oil

Step 1 – Jack up the car

Use your jack to raise the front of your car, enough that you can fit under it, then secure it with jack stands. The jack goes right behind the front wheels, and the jack stands go directly next to it, inwards, on the metal piece dedicated for it.

Step 2 – Drain engine oil

Open the oil cap on top of the engine, then slide under the car and locate the drain plug on the oil pan. It is located on the side of the pan, towards the passenger side. Place the drain pan underneath it, then loosen the drain plug slowly until it's removed. Let the oil drain completely.

Step 3 – Replace oil filter

The oil filter is located on the driver's side of the engine. Remove the engine cover by pulling it up, it's held in place by a few clips, then use your socket to turn the oil filter counter-clockwise to remove. Install the new filter in place, then tighten it. Make sure to rub the filter's rubber gasket with some oil, as this will ensure it doesn't dry and crack.

Step 4 – Refill engine with oil

Make sure the drain plug is closed and tight, then refill the engine with fresh fluid from the top. Run your engine for 30 seconds, then check the level on your dipstick. Top off if you need to.
