Under the hood
30 Only use oils specifically approved for your
vehicle model.
Your BMW Center will be glad to advise
you about oils currently approved for your
vehicle.<
You can also call BMW of North America toll-
free at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Alternative oil grades
If a high-performance synthetic oil approved by
BMW should be unavailable, you may use small
volumes of other oils for topping up between oil
changes. The following data must appear on
the packaging:
>Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or SAE 10W-40
>Specification
preferred: API SJ/CF
alternative: API SJ, also SK, SL, S...
Low ambient temperatures
The oils used by BMW at the factory for your
vehicle model can be used at virtually all ambi-
ent temperatures. However, if the vehicle is
operated for a longer period at temperatures
below –47/–206, your BMW Center will be
glad to recommend a suitable oil.
