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 oil level can be displayed when the engine
is at operating temperature. Constant short-
distance driving or a very sporty driving style
can make it impossible for a measurement to be
taken.
Displays in instrument cluster
You can display the current oil level in the
instrument cluster.
1Oil level
2Maximum marking
3Minimum marking
4BC button
Press the button4 in the turn signal lever
repeatedly until the display for the oil level
appears in the instrument cluster.
Manual transmission: the fluid level will be
shown in the lower display.<
The oil level must be between the two marks.
A new measurement is automatically taken
after each engine start.
Possible displays
1Oil level OK
2Oil level is being determined.
This process can take approx. 1 minute
when stopped on a level surface and
approx. 5 minutes while driving.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
3Oil level at minimum:
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below Add at least
0.5 US quart/0.5 liter. Otherwise the oil
level control may not display the new value
correctly.
If the oil level displayed is below minimum,
add engine oil immediately. Failure to do so
may lead to engine damage.
4Oil level is too high
Have the vehicle checked immedi-
ately; otherwise, engine damage may
result if too much oil has been added.<
5No value can be determined at this time.
Engine is not yet at operating temperature.

Fast measurement
In addition to the automatic measurement, you
can also determine the current oil level manu-
ally, e.g. after adding engine oil, but with a lower
degree of measuring accuracy.
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Allow the engine to run at idle.
3.Press the BC button in the turn signal lever
repeatedly until the oil level display is
shown in the instrument cluster.
4.Press the BC button for at least 2 seconds.
The oil level is determined. A clock symbol
is displayed during the measurement.
5.After approx. 1 minute the current oil level is
displayed.
Displaying via iDrive
iDrive, for operating principle refer to page16.
1.Press the button.

Possible messages
>"Engine oil level O.K."
>"No measurement available: Updating
engine oil level measurement...":
Engine oil level is being measured. This
process can take approx. 1 minute when
stopped on a level surface with the engine
running and approx. 5 minutes while driv-
ing.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
>"Oil level at the minimum! Refill with 1 quart
of engine oil.":
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below. Add at least
0.5 US quart/0.5 liter. Otherwise the oil
level control may not display the new value
correctly.
If the oil level displayed is below minimum,
add engine oil immediately. Failure to do so
may lead to engine damage.
>"Engine oil level too high":
Have the vehicle checked immedi-
ately; otherwise, engine damage may
result if too much oil has been added.<

Under the hood
212 >"Please observe recalculated service inter-
val for engine oil":
Do not add engine oil. Before continuing to
drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page72. Have the
system checked as soon as possible.
Adding engine oil
Do not add oil until a value slightly above the
minimum of 0.0 US quarts/liters is displayed by
the oil level measurement. In this area a mes-
sage is also shown on the Control Display.
Add oil within the next 125 miles/200 km,
otherwise the engine could be damaged.
Add a maximum of 1 US quart/1 liter of oil, oth-
erwise the engine may be damaged by adding
too much oil.
Add at least 0.5 US quart/0.5 liter of oil, other-
wise the oil level check cannot reliably display
the current oil level.<
Please conduct a quick measurement
after adding engine oil to check the oil
quantity added and to update the display.<
Continuous exposure to used oil has
caused cancer in laboratory testing.
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 observe 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 spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives; under some cir-
cumstances, they can damage your
engine.<
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance 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.
Viscosity grades
The viscosity is a measure of the thickness of
the oil and is specified in SAE grades.
Approved oils belong to the SAE grade
10W-60.<
Alternative oil types
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes.
Only use oils with the following specifications:
>Viscosity
preferred: SAE 10W-60;
alternative: SAE 10W-40, SAE 5W-50 or
SAE 10W-50
>Specification
API SJ/CF, API SK/CF or higher
Low temperatures
The oils used by BMW from the factory for your
M6 can be used at virtually any ambient tem-
perature. However, if the vehicle is operated for
a longer period at temperatures below –47/–
206, your BMW center will be happy to rec-
ommend a suitable oil.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page72:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally required tests depending on local
regulations
Service data in remote control
Your vehicle stores the information required for
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. For this reason, when you take your vehicle
in for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date is set correctly, refer
to page79, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<
