The PITA about the transfer case is that xdrive fluid is $60/liter (you need less than 1 liter iirc) and then you need to reset the clutch adaptations after putting in the new fluid. That has to be done with a scan tool with BMW software, not a generic one iirc. I have a buddy with a shop so it's easy for me, but DIY folks need to know it's not like changing out the diff fluid.

Good to know I will probably do the diffs at the same time as well. I will take it somewhere to do it all as well but im sure its going to be expensive.

Has anyone used motul 5w-30 or motul products in general

I’ve looked all through the owners manuals to find a capacities page. This does not seem to exist, specifically the oil capacity for the 2023 M550i. I can find all kinds of info on oil type, checking level, etc.

There is nothing I can find referring to oil change, oil capacity, with and without filter. How does one know how much oil to use without manufacture reference?

Look in the index at the back of the OM for capacities. Should be there.

I’ve been looking in the pdf version in the drivers guide application. There is nothing on capacities in that OM. I’ll look in the paper version to see if it’s different.
