Cool. I'm putting it in my rear diff this morning then. Liqui Moly's website recommends their 75w-140 (LM4420) for F3x differential(s), but I couldn't find it for sale anywhere. Based on this thread I went ahead and got 75w-90 (LM2048).
EDIT: Looks like LM4420 is sold in the U.S., however its English part number is LM20042. Liqui Moly recommends this 75w-140 for F3x differentials, however also says that it's really intended for LSDs. Those of us with open diffs should be fine with 75w-90, which is part number LM2048.
