Engine oil CoolantSpecified engine oils The quality of the engine oil is
extremely important for the function
and service life of an engine. Based on
extensive testing, BMW approves only
certain grades of engine oil.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Only use oils with
the API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"special oils" which have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this

Viscosity ratings Viscosity is the oil flow rating as estab-
lished 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.
Do not add coolant to the cooling
system when the engine is hot.
If you attempt to do so, escaping
coolant can cause scalds. To avoid the
possibility of secondary damage, never
use anything other than factory-
approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your BMW center is familiar
with these specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their original con-
tainers and in a location which is out of
reach of children. For this reason, do
not spill antifreeze with corrosion inhib-
itor on hot engine parts. It could ignite
and cause burns.<
