Which differential and manual trans fluid to buy?
I have a 6MT '21 M4 with ~15K miles. It has been to 4 track days last year and plan to do 8-10 days this year. Is it worthwhile to change diff and manual trans fluid once per year n a car that is both a daily driver and weekend track car? And if so, which specific fluid is needed?
A search on Turner motorsports yields this: https://www.turnermotorsport.com/BMW...erential-fluid And bimmerworld recommended this for trans fluid: https://www.bimmerworld.com/Red-Line...uid-Quart.html And this for diff: https://www.bimmerworld.com/Red-Line...Oil-Quart.html Not sure if this is correct though.

Just did the diff and transmission fluid along with an extra oil change at 5k miles.
Definitely some metal in the diff so worth doing the fluids despite having the diff fluid changed at break in. It was super easy for both with plenty of room so you don't need any special low profile hex sockets. |

Diff fluid and Transfer case fluid for xDrive models is indicated at the 5th oil change or 50k miles. Maintenance schedule does not list trans fluid at all.
