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

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

The engine must be at ambient tempera-
ture.
