X5M oil weight?

[StatenEye]

Last night I went to pick up oil to top off. Upon researching there seems to be conflicting stories on which oil is RECOMENDED by BMW for this engine. To be FRANK, not rude; I'm not interested in any opinions, I'm just looking for the correct oil for this engine. Can someone with the correct and only answer chime in? Thanks and apologies for the blunt nature of this post but I do not have access to my manual until the weekend and I was hoping for a simple answer from past threads.

Yea i read that thread last night and got frustrated when I saw dealers putting different oil in the same engine so I closed it.

It seems 5w30 is the answer. Thanks

Correct

This all started because the older M engines were naturally aspirated and high revving. The required super thick oil, like 10W-60. The S63 does not require this type of oil since oil slinging is not an issue like it is on an S54 or S85.

Called the (reputable) dealer earlier today and without hesitation confirmed 5W-30.

Common response from (uneducated) shops will state it needs 10W-60 as Crazy mentioned, since they assume its high revving.

I use royal purple 5w-30 in my N63

Here's a quick way to find the manual

Pick up your year. There's an addendum to read also.

At page 272, under the heading:
“Approved oil types,” the references
to “Approved” should be read as
“Suitable.” Immediately preceding
the “Gasoline engine” chart, the
following sentence should be
inserted: “Add engine oils that meet
the following oil rating
standards: . . .” The reference to
“BMW High Performance SAE 5W-
30” should be disregarded.

At page 273, under the heading:
“Alternative oil types,” the text
preceding the chart should be
disregarded, and in lieu thereof
should be read as follows: “If an
engine oil suitable for continuous
use is not available, up to 1 US
quart/liter of an engine oil with the
following oil rating can be
added: . . .” The reference to
“specification” should be read as
