Awesome Thanks! so there isn't a such thing of using a diff oil from the older days that doesn't contain the FM booster? Because obv the SIB was released for cars making noise and using the standard oil. Has BMW switched over and made this additive oil now standard?
Just making sure that when I go in for my routine maintenance they don't put some standard type of oil in there and make sure they use the FM booster diff oil.
