Thanks for posting.

Bmw also says lifetime fluids in the tranny and diff’s.

I guess I’ve been lucky. I made 600-700-800whp out of Bmw M engines and NEVER witnessed anything like this. 1-2qts in 1k.

I guess since BMW has a service bulletin, it’s acceptable.

please see "SI B11 03 13" for your own personal reference. That specifies our oil usages, set at 1 liter per 750 miles for all "M" motors, and n63 motors.
