Dana 300 how much oil and how to refill it?

Its my first time changing fluids
I have already drained my dana, it has very little oil in it, about 200 ml or less.

I also have already refill it but I'm not sure I did it properly :/

I did not remove the Dana from the Jeep, I pour oil into the Dana until it stared to leak from the refill port.
The dana is tilted, so I'm not sure I out enough oil in it.

It took 1 Qt bottle + 3/4 Qt bottle

Its that enough? I have seeb post that says it takes 2Qt and some that says 4Qt :/

Also my shopping for my oil, I saw some aditives,would you recommend any?

The D300 officially takes 3.9 pts. So if you did 1.75 qts., that's almost full. (Sorry, my conversion to liters is not the best. Silly American system.)

What type of oil did you use? I have read other people's posting that say to use 10/30. Some use ATF. The FSM say to use the same gear oil as the T4/T5 trans - 75/90.

I put Pennzoil Syncromesh in both the trans and tcase.

I did not have to drop the tcase. I just placed a funnel under the drain plug to catch it in a container. The fill plug (as you know) is just above the drain.
