Even when he doesn't personally benefit. I have multiple analysis reports from Blackstone that confirm the oil is close to being depleted at the 8,000 mile point. 7,500 miles is a convenient threshold for me, so I do changes at that point. Why do you do changes at 7,500 miles?

My SA would benefit from me betting more frequent oil changes. Yet, he discourages me from doing so because based on his expertise and experience, he does not view it as necessary.
I do changes at 7,500 miles because I personally think it makes good sense. I also see little reason not to. For $90 extra a year, why give it a second thought? In fact, I will stick to Mike Miller's schedule as long as I own a BMW.
To be clear, I am not trying to argue that BMW's oil change schedule is optimal. I simply agree with Sunny's point - there really isn't any compelling evidence to the contrary.
I also rotate my tires every 5,000 miles and I plan to swap out the water pump early as a preventative measure.
Better safe than sorry!
