My 745LI is approaching the 100,000 mile mark. I have changed all the fluids except the differential. Can someone tell me which gear oil to use. All I have been able to find is that the original fluid was lifetime.
Thanks,
Butch

Butch,

Lot's of folks (including myself) use the Redline 75/90 weight gear oil.

It's also recommended by Mike Miller, who writes the Tech Talk section of Roundel magazine.

Hope that helps.
