Dexron VI isn't a full synthetic; it's a synthetic blend.
I drained approximately half of the total amount in the transmission.

I didn't get a TBN done on this sample; Blackstone charges an extra $10 for it and I changed the ATF at half the BMW service interval ... 'lifetime' is defined by BMW as 100K miles.
Since I also changed the filter I anticipate any future tests to come back with less contaminents, especially since the first few thousand miles is where most of the wear occurred.
