2-automatic
transmission: only use ATF approved to MB 236.10, MB 236.12 synthetic dextro III transmission fluid may be substituted. (here says
transmission fluid. never says oil).
3-manual transmission fluid: only use fluid approved to MB 236.2. SAE 5W-20 engine oil, meeting API SL or GF-3, may be substituted. (here is fluid-and engine oil). so manual uses oil..
4-rear axle fluid: only synthetic SAE 75W85 axle lubricant that meets MB 231.1 (here is called lubricant)
so, which is oil and which is not? and rear axle takes lubricant, so does not say oil.
so, which has to go with which SAE? there is no mention on which.
and the manual is the bible.
I have not seen an oil that is not a fluid.
Where an oil gets thick enough to be called a grease I have no idea, or is there something in grease that defines it as a grease.
Item 4 says ‘rear axle fluid’ so it is an oil.
Oils and greases are lubricants, greases are not used in any of the four components listed.
