Do not use oil additives; under some
circumstances, they can harm your
engine. <
Viscosity grades
The viscosity is a measure of the thickness of
the oil and is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.
<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns. <
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
present a health hazard. <
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives. <
Checking coolant level
1. The engine must be at ambient tempera-
ture.
2. Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3. The coolant level is correct when it lies
between the Min and Max mark, also refer to
the drawing next the filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5. Turn the cap until it clicks.
6. Have the reason for the coolant loss elimi-
nated as soon as possible.
