Topping up engine oil
Viscosity ratings
Viscosity is the oil flow rating as defined 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.
Wait until the level has dropped to just on
the lower dipstick mark before adding oil.
In this area a message also appears on the
Control Display.
Coolant
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.<
Store oil, grease etc., well out of the
reach of children; always observe all
warning labels on the containers.<
Coolant consists of water and the addition
of antifreeze and anticorrosion agent. Not
all commercially available additives are
suitable for your BMW. Ask your BMW cen-
ter for suitable additives.
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW continu-
ously approves specific oils after confirm-
ing their suitability for use in its vehicles
with extensive testing.
Only use suitable additives, as other-
wise engine damage may result. The
additives present a health hazard; observe
the instructions on the containers.<
Use only approved BMW High Perfor-
mance Synthetic Oil.
Always observe all applicable envi-
ronmental rules and regulations when
disposing of used coolant additives.<
If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Checking coolant level
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which have been approved.<
