Now have a BMW M Performance LSD that I will be having installed on my M240i. Two questions:

1. What is the capacity in liters/quarts for the LSD differential?

2. Recommendations on oil (manufacturer, visc, etc)?

Thanks very much.

I found this post for the M235i that suggests the LSD comes with "lifetime" fluid. The part number for the M240i is different however.

I had mine changed after 2,500km.

Thanks. What oil did you use for the replacement. LSD oil I assume, but was it 75-95 or 75-140? Brand?

I used the OEM BMW differential oil, I think it was 75W-85, but not sure.

Ditto, OEM fluid and changed at 25k kms.

For the MT gearbox I'll be using a Redline gear oil instead. Not changing until next winter, though..

Only thing I would caution going non-OEM on gearbox oil, it can make it tough to shift into 1st when cold.

Yea, typically the "track" duty gear oils take a while to warm up. Redline "synchromesh" (I think) is what I used in the past, never effected shifting, negatively, and if anything made the VW/Audi gearboxes much smoother..
