Does my car have LSD?

[Jason M Surprise <jmsurpri@xxxxxxxxxxxxxxxx>]

I have a 94 325i that I bought used a couple years ago.  I am thinking
of replacing the final drive gear oil, but I've heard that what you use
depends on whether you have limited slip or not.  How do I figure out if
I have a LSD on my car?  What gear oil do you recommend?

Thanks,
Jason
