Kinda hard to say for certain, but has worked well for me.
In addition to my M550ix, I have a daily driven 2001 540 M-Sport I have owned basically since new. I have followed Mike Miller's recommendations on transmission/differential, brake, coolant and oil changes, as well as other recommended maintenance schedules and I am now 500 miles shy of 360,000 miles. Original engine and transmission, never been rebuilt. I did have to have the timing chain guides replaced at 263,600 miles, but that is way later than most...who have them let go at 150k to 200k .
I perform oil changes every 7,500 miles which is half the factory recommendation and use factory approved LL-01 BMW spec oil.
Transmission and differential were serviced every 30k for the first 180k miles, or so, then I went to every 50k...thinking that 30k recommendation was overkill. His current recommendation is every 50k to 60k on transmission, differential and transfer case (x drive). Coolant change every 2 years I believe is his recommendation, I have since gone to 4 years. A flush is recommended mostly for the heater core, as they are prone to plug when the cars get on in years and miles.
