Return the dipstick to the guide tube,
inserting it as far as it will go.

As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.
The oil volume between the two marks on the
dipstick corresponds to approx. 1.1 quarts/
1 liter.

Do not fill beyond the upper mark on the
dipstick. Excess oil will damage the

engine.

Adding engine oil

Do not add oil until the oil level has dropped
almost to the lower mark on the dipstick, refer to
page

Add oil within the next 30 miles/50 km,
otherwise the engine could be dam-

aged.

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 materials
so that they are inaccessible to children. Com-
ply with warning labels and the information on
the containers.

Comply with the applicable environmen-
tal laws regulating the disposal of used

oil.

Oil change

Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.

Approved engine oils

The quality of the engine oil is extremely impor-
tant for the function and life of an engine. Based
on extensive testing, BMW has approved cer-
tain grades of engine oil.
Use approved High Performance Synthetic Oil.
If you are unable to obtain an approved 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 concern-
ing the specific High Performance Syn-

thetic Oil or synthetic oils that have been
approved.

BMW engines are designed to operate
without oil additives; the use of additives

could even lead to damage in some cases.

additives are hazardous to health.
