amount of diff oil needed

[davem]

I want to give my differential an oil change, does anybody know how much I'll need exactly? I bought two quarts.

The cars is a '91 325i w/ LSD, whatever size came with the automatics.

Just fill through the upper plug until it runs out.

Just fill through the upper plug until it runs out.

Yeah just drain fully, and when filling it up, continue adding oil until it comes out of the upper plug hole.

Oh, my question was more geared towards making sure I had enough so that I didn't have to go and get more while doing the job. I've heard that it's 1.8 quarts but I wanted to make sure.
