I've used Mobil 1, Redline, and Castrol synthetic fluids in my LSDs over the years and they've all been fine.  

I say just get a quality name synthetic and call it a day.

I do not have one.  Thinking Redline.  Any particular weight/vis?

Redline 75W-90 is a good choice.

i have made a mistake while ordering oil, and i put Castrol SAF-XO (for final drive without limited slip differential) instead of a SAF-XJ (for and without LSDs). They are both full synthetic 75W90. Do you think I should change the oil, or it can stay? It's not really cheap, so...
