Adding engine oil

Wait until the level has dropped to just
above the lower mark before adding oil.
However, you should never let the oil
drop below the lower mark.

BMW engines are designed to
operate without oil additives; the

use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the automatic
transmission, the differential, and the
power steering system.

Recommendation: have the oil changed
at your BMW center.

Continuous exposure to used oil
has caused cancer in laboratory

testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oil, grease, etc., out of
reach of children. Comply with all warn-
ing labels and information on lubricant
containers.

Comply with the applicable envi-
ronmental laws regulating the dis-

posal of used oil.

Specified engine oils

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

Use only approved BMW High Perfor-
mance Synthetic Oil.

If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small volumes of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.

Ask your BMW center for details
concerning the specific BMW

High Performance Synthetic Oil or syn-
thetic oils that have been approved.

You can also call BMW of North Amer-
ica toll-free at 1-800-831-1117 or visit

Viscosity ratings

Viscosity is the oilflow rating as estab-
lished in SAE classes.

The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.

Approved oils are in SAE classes
5W-40 and 5W-30.

These kinds of oil may be used for driv-
ing in all ambient temperatures.
