In the engine compartment

The oil volume between the two marks on
the dipstick corresponds to approx.
1.1 US quarts / 1 liter. Do not fill beyond
the upper mark on the dipstick. Excess oil
will damage the engine.

Adding engine oil

While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never allow
the oil level to fall below this mark.

BMW engines are designed to oper-
ate without oil additives; the use of

additives could even lead to damage in
some cases. This also applies to manual
and automatic transmissions and to the dif-
ferential.

Continuous exposure to used oil has
caused cancer in laboratory tests. For

this reason, thoroughly wash any areas of
skin that come into contact with oil using
soap and water.
Always store oils, grease and similar mate-
rials so that they are inaccessible to chil-
dren. Comply with warning labels and the
information on the containers.

Comply with the applicable environ-
mental laws regulating the disposal of

used oil.

Approved engine oils

The quality of the engine oil is extremely
important for the function and life of an
engine. Based on extensive testing, BMW
has approved certain grades of engine oil.

Use approved "BMW High Performance
Synthetic Oil".

If you are unable to obtain an approved
BMW High Performance Synthetic Oil, you

may use small volumes of other synthetic
oils for topping up between oil changes.
Use only oils with the specification API SH
or higher.

Ask your BMW center for details con-
cerning the specific BMW High Per-

formance Synthetic Oil or synthetic oils that
have been approved.

escaping coolant can cause burns.
Antifreeze and anti-corrosion agents are
hazardous to health. You should always
store them in their original containers and
in a location inaccessible to children.
Antifreeze and anti-corrosion agents are
flammable. For this reason, do not spill
them on hot engine parts. They could ignite
and cause burns. Comply with the instruc-
tions on the containers.
