Possibly true, but my old N47 f10 was diagnosed by BMW at 53k miles - I knew the car from new and it had been the opposite of abused by the owner before me that had it from new. Admittedly, it had gotten to low 40's with servicing at BMW recommended service intervals. I do agree that this is an important additional factor in long term health, but it never said on the display or the handbook "Maybe change the oil more frequently so that the chain doesn't break".
