I run a 140w oil in both my diffs on the ute. and apply it using a 500ml syringe.
140w oil is thick and being that the front diff is 5.4L it requires alot of strength to suck and push it through the syringe so what I do is fill my esky with hot water and leave it in the sun for a while. this will heat the oil making it thinner and therefor easier to move through the syringe.
