LSD for S13 what gear oil you use?

[friscogiant]

I just picked up an LSD and would like to service it after install. I heard you have to use an additive to the gear oil. What's your combo.

I did a search but I suck b/c only one thing I found was on an open diff.

Thanks in advance.

To use only what is specified for your differential is my goal. Which I don't know. It's a VLSD by the way. Anyone got the manual recommendations. Second-guessing the engineers that designed the differential and filling up the case with the wrong gear oil can ultimately add up to an expensive guess. Which I don't want to do.

use any oil you want. prob something like mt90 gear oil. since its VLSD it doesnt need any special oils or modifiers since the VLSD is a sealed unit. only clutch units require special fluid/modifiers.have fun.
