trying to find the right oil for the differential, found this:
from page 245 of manual, synthetic SAE 75W85 that meets MB 231.1 specs.
and those specs are here:
https://bevo.mercedes-benz.com/bevolisten/231.1_en.html
very precise; specific type.
but also found a thread in which several fellows mention that they use assorted kinds. will try to bring those comments.
my doubt comes from the fact that the manual is very specific so i guess that we must be very precise on the use of the oil recommended by MB.
comments?
