So I am confused why you are linking to a UOA that shows a failed fluid???? Lower viscosity than is required; higher insolubles; higher wear metals. Their averages are based on 30k miles...this UOA is 2x that in length but wear is 2x, 3x, 5x more.... what are you seeing that says 70k is fine



PS I am a bit of a fanatic on ATF- if there is data supporting BMWs position, then lets see it...but I refuse to allow causal assertions go unchallenged.
Keep it as simple as possible...but no simpler.
