dana 44 lsd

Hello, Looking at doing my axles oil change and I'm wondering: The peoples who did it in the JL and got the factory Limited Slip Differential what oil did you put in and did you need to add some friction modifier to the oil ? trying to know if I can get away with just the standard friction...

Reading on my Sport build sheet, I have open differentials. However, reading about the SelecTrac Traction Control, it basically describes it like having a computer controlled LSD. So would adding a LSD prove any benefit? Or does the Traction Control do it all already? (4xe specific)

2018 jlu sport axles. Front dana 30, and rear dana 44 limited slip. Have about 12000 miles. $1000 obo. For both. Coming out of my vehicle on march 16.
