I run a 10 k oil in my center diff daniel. That seems to work will. I used ue oil to. I am not sure on the stock diffs you have for they only have the 4 spyder gears in them I think. That would require the thicker oil for the same effect as the 6 spyder diffs.

Could you explain on the difference between the other two companys. Like is it thinner or thicker. And what have you tried with results you got.
