Please don't make blanket statements. As stated, non-M open diffs and M LSD are different and need different fluid. The FM Booster was added to reduce noise/diff whine. Many M3 owners switched to Redline or RP and noticed add'l whine after few thousand miles, fix = OEM fluid with FM Booster.

OP, your car will work fine with non-OEM fluid but I suggest you use it in case you find non-OEM fluids making un-wanted noise. Changing it once with more $ fluid is still cheaper than changing it twice with non-OEM and then OEM.
