Engine oil

Engine oil consumption depends on driving style and driving conditions.

Checking engine oil level

Your vehicle is equipped with an electronic oil level check. The condition for the most accurate indication
of the oil level possible is measurement with the engine at operating temperature, i.e. following an uninterrupted drive of at least 6 miles/10 km. You can display the oil level on the Control Display while driving or when stopped on a level surface with the engine running.

  1. Press the MENU button. This opens the start menu.
  2. Press the controller to open the I menu.
  3. Select “Service” and press the controller.

Possible messages
  • “Engine oil level O.K.”
  • “No measured value available: Updating engine oil level measurement…”: Engine oil level is being measured. This process can take approx. 3 minutes when stopped on a level surface and approx. 5 minutes while driving.
  • “Oil level at the minimum! Refill with 1 quart engine oil.”: Add 1 quart/liter of engine oil at the next opportunity.
  • “Engine oil level too high”:

⚠ Have the vehicle checked immediately; otherwise, engine damage may result if too much oil has been added.

  • “Please observe recalculated service interval for engine oil”: Do not add engine oil. Continued driving is possible. To do this, observe the recalculated remaining mileage until the next oil change service.
Topping off engine oil
Under The Hood BMW 2006 6 Series6

Do not add 1 quart/1 liter of oil until a corresponding message appears on the Control Display.

⚠ Add oil within the next 125 miles/200 km, otherwise engine damage could result.
⚠ Continuous contact with used oil has caused cancer in laboratory tests. For this reason, thoroughly wash exposed areas of skin with soap and water after such work. Keep oil, grease, etc. out of reach of children
and heed warnings on containers. Failure to do so could pose health risks.

Oil change

Have oil changes carried out only by a BMW center or a repair shop that works in accordance with BMW guidelines and uses appropriately trained personnel.

Approved engine oils

The quality of the engine oil selected has critical significance for the operation and service life of
an engine. BMW continuously approves specific oils after confirming their suitability for use in its vehicles with extensive testing. Use only approved BMW High Performance Synthetic Oil.

If BMW High Performance Synthetic Oil is unavailable, you can add small quantities of other synthetic oils between oil changes. Use only oils of the specification API SH or higher.

▶ Your BMW center will be happy to answer detailed questions on BMW High Performance Synthetic Oil or approved synthetic oils.

You can also call BMW of North America at 1-800-831-1117 or visit the website at www.bmwusa.com to obtain this information.

⚠ Do not use oil additives; under some circumstances, they can harm your engine.

Viscosity grades

The viscosity is a measure of the thickness of the oil and is specified in SAE grades. The choice of the right SAE grade is based on the climatic conditions in the region in which you normally drive your BMW.

▶ Approved oils belong to the SAE grades 5W-40 and 5W-30.

These oils can be used for driving at all outside temperatures.


⚠ Do not open the cooling system when the engine is hot. Escaping coolant can cause burns.

Coolant consists of water and coolant additive. Not all commercially available additives are suitable for your BMW. Ask your BMW center for suitable additives.

⚠ Only use suitable additives; otherwise, engine damage may result. The additives present a health hazard.

Always observe all applicable environmental laws and regulations when disposing of used coolant additives.

Checking coolant level

  2. Turn the cap of the expansion tank counterclockwise to allow any accumulated pressure to escape, then continue turning to open.
  3. The coolant level is correct when it lies between the Min and Max mark, also refer to the drawing next the filler neck.
  4. If the coolant is low, slowly add coolant up to the specified level – do not overfill.
  5. Turn the cap until it clicks.
  6. Have the reason for the coolant loss eliminated as soon as possible.
