Approved 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.
Only use 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 in between oil
changes. Only use oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for more details concerning BMW
High Performance Synthetic Oil or other
approved synthetic oils.

BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.

Viscosity classes
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class depends
on the climate conditions in the area where you
typically drive your BMW.
Approved oils belong to SAE classes
5W-40 and 5W-30.
<
These oils can be used for driving in all ambient
temperatures.
Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.

Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sports
