Second run, this time over a year and a touch under 10K miles. 1y/10K is the updated OCI where as this year the manual states 2y/20K miles: guess zee german engineers got their way for one year until the service people cried waaaaaah, lost $200 oil changes
Looks darn good to me, and the M1 seems to have far more life in it. Car has a mixture of 100 day HWY commutes (when I get it) and 20m mixed commutes (her DD). Engine is best when run from 4500-6800
Metals up slightly but that trends with a low average miles in their DB. Both of these are dealer bulk which I assert is M10/40 given the recommendation and deals. I did this one myself and used 8qt of autozones finest on sale M1.
Blackstone comment (I like one comment in particular, very BITOG-ish) :
We are seeing a little more iron in this sample than last time, though we think the longer oil run is probably the biggest factor in that. Iron tends to track directly with time on the oil. The longer the run, the more iron you can expect to see. Remember, averages are based on just under 6,000 miles on the oil (wimps), so your iron reading isn't going to look as good as average after using longer runs. We don't think it's a problem at all. The TBN is good at 4.4 since 1.0 or less is low. Aim for 10,000 miles next time, even if it takes longer than a year. Nice engine!
