Or a part number?

And the exact quantity you had to buy?

I used it in my fluid change about 2k miles ago. I will let you know 2k miles ahead of you if it blows up lol
Any problems so far?

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.

Still good for me too! About 4k miles since the fluid change.
