fluid for rear end

[gundy5151]

2001 z3 3.0 with sport package. Do I have a limited slip rear end and if so electric or mechanical ? What type of rear end fluid? Thanks guys.----- Gundy

Plug in your vin into a decoder and it should tell you if it came with one.

If it did, I believe it is a Torsen differential.

Evidently this does have a limited slip. What type of fluid. Getting contrary answers in service manual and parts guys. Limited slip would be heavyer fluid ??

I have an '06 3.0si and ran into the same issue a couple years ago (conflicting information); ultimately I went with Royal Purple Max Gear Oil 75w 140 and have not had any issues so far...
