Mine is at 1900 and I'm not changing the oil.
My 440i is completely my up to 5200 miles and says oil service in another 15000 miles (although that could change depending on driving conditions over time) but I’m not inclined to have an oil change done as yet. I’ve always stuck to the service schedule for every one of the twenty or so BMWs I’ve had over the past forty years and have never had any issues.
As for diff and transmission oils, never ever changed them but then again never ran a BMW for more than about 45k miles over the years.
BMW state the diff and transmission oils are ‘sealed for life’….hmm?…not entirely convinced by that however still wouldn’t be thinking about changing either of those until the car had several tens of thousands of miles on it.
