Redline 75w90 diff I crazy? I crazy?

I spend 4 hours per weekday in my x3 and think I know her well after 102k miles.

Two weeks ago, I replaced the diff fluid with redline 75w90 (previous changes were with BMW fluid by dealer) and my automatic x3 seems to now be an absolute rocket ship off line. I have always had a "lag" when I hit the go pedal but now I don' wife even noticed.

Okay, once I crazy? If I am not I highly recommend redline diff fluid!
