190E 16 valve LSD differential gear oil question
I am almost ready to install a LSD diff from a 16 valve into my 190. MB recommends their own gear oil but no one seems to know the weight of the oil, the bottle does not say (just says GL-5).
Of course I don't really want to run the OE MB LSD gear oil, I would prefer to use Mobil 1 synthetic, which is a 75w90 weight and is listed as exceeding GL-5 specifications and also is listed as being compatible with LSD.
Anyone have any comments?
