Redline 75w90 diff fluid...am I crazy?
Ok...am 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't...my wife even noticed.
Okay, once again...am I crazy? If I am not I highly recommend redline diff fluid!
