Well I changed the rear end oil in my 1951 Farmall h a few months ago. I am pretty sure it still had the original stuff from the factory. I thought I would be smart in doing this because it too looked like cake batter.
Refilled it with 90 weight mineral gear oil. Tranny/rear end now makes quite a bit more whining noise compared to what it used to. I wish I would have left the cake batter stuff in there as my stuff was not water contaminated (but it both looked and smelled nasty). Unfortuantely, I had already discarded the cake batter stuff or I would have simply put it back in there had I still had it.
Anyway, if you dead set on changing it then I would go with 85W-140 (in GL1-through GL-4 spec grades) from NAPA or somewhere similar. Most of the GL-5 grades of oil that you will find at all the discount marts can eat brass and bronze bushings in your tranny....so I personally would not risk those....but if you feel lucky risking a ruined tranny in order to save a few dollars then go for it.....
I will eventually change my ole h again when time and money allows. Plan to go with 85W140 (GL1-through GL-4)
