Exactly!
Most of our miles up until the first CSB were 40mi (one way) trips on back country roads with a lot of hills and included a fair amount of towing of heavy loads (e.g. 2 tons + trailer). Yet our 1st CBS was not till nearly 11k.
I would have thought that towing in hilly terrain would have reduced the miles to the 1st CBS Oil Service. But obviously BMW knows better*
