Hi, my vehicle is a 2015 BMW 535i Xdrive with 96,000 miles.
I'm planning to get a fluid change and search about it.
Here's a question.

For Transfercase, I think I need 1L.
I ordered BMW DTF1 Transfer Case Fluid (1 Liter)
STC-OIL0005.

For front, rear differential fluid, 1L for each.
I ordered 75W90 Fully Synthetic Hypoid Gear Oil (1 Liter)
MOL-LM22090 two of them.

But my local mechanic told me that I need a total of 4qts for front and rear differential.
And 2 qts for transfer case.

Do I need to buy more? or 1L each is enough?
Thanks in advance.

I did my oil change for rear diff for F10 550i LCI and it took 1 quart and its more that enough. I remove the existing oil and it comes around less than 1 qrt. I used redline 75w90. and it works fine.
