Copied from another post about motor oil.
Does anyone have a link to an on line parts diagram for the E90?

Here is the response I got back from Mike Miller, the BMW Car Club of America magizine "Roundel" Tech Talk expert....

Hi Mike,
You'll get as many answers as people you ask about motor oil, perhaps more. All I can tell you is what I do. I adhere to the BMW maintenance schedule that was in force before BMW starting paying for maintenance, and then lengthened or eliminated all the intervals. I perform a break-in service at 1,200 miles that includes engine oil and filter, manual gearbox oil, and differential oil changes. I don't mess with automatic transmissions. Thereafter, I change gearbox and differential oil every 30,000 miles.
And by the way, you and I are old school, and it's not nonsense. Today's marketing baloney of "maintenance free cars" is nonsense. Anything can be maintenance free -- just don't maintain it.
Best regards,
Mike Miller

Bottom line, if you like your car, care about resale value, change your oil. At a bare minimum, change it every 7,500 miles...
