Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
1.Park the vehicle on a level surface with the
engine warm, i.e. after an uninterrupted
drive of at least 6 miles/10 km.
2.Switch off the engine.3.After approx. 5 minutes, pull the dipstick3
out and wipe it off with a clean lint-free
cloth, paper towel, or similar material.
4.Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two
marks on the dipstick.
The oil quantity between the centers of the two
marks on the dipstick, refer to arrows, is approx.
1.6 US quarts/1.5 liters.
Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.<

Topping off engine oil
Wait until the level has dropped to just above
the lower dipstick mark before adding oil. When
it falls to this level, a message also appears on
the Control Display.
Refill the oil within the next 125 miles/
200 km, otherwise engine damage could
result.<
Store oil, grease etc., well out of the reach
of children; always observe all warning
labels on the containers.<
Oil change
Have oil changes carried out only by a BMW
center.
Specified 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.
Use only approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil between oil
changes. Use only oils with the API SH specifi-
cation or higher.
Ask your BMW center for details concern-
ing the specific BMW High Performance
Synthetic Oil or synthetic oils which have been
approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this information.BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
Viscosity ratings
Viscosity is the oil flow rating as defined in SAE
classes.
The selection of the correct SAE class depends
on the climatic conditions in the area where you
typically drive your BMW.
Approved oils are in SAE classes 5W-40
and 5W-30.<
These oils may be used for driving in all ambient
temperatures.
Coolant
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 suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
