First Blackstone Oil Analysis of German Castrol @ 7680 miles with 6000 miles on the oil. Looks like some break-in metals are still shown in the oil. While TBN was still acceptable, it appears that this oil may not go the full BMW 15K mile OCI. I was encouraged that the flash point was still very high, and Fuel % was very low indicating no fuel dilution issues in this sample (a commonly reported problem with this engine). I think the GC is doing pretty well.

Don't be alarmed by all the highlighted numbers in the
first sample from your BMW. It takes a few oil changes
for all of the excess wear metals (due to new parts
breaking-in) to wash from an engine. Silicon is from
sand-casted parts and sealers used when assembling your
engine and it too, with subsequent oil changes, should
read a bit lower. Universal averages for the 3.0L are
based on an oil run of ~5,500 miles. The TBN read 4.1,
which shows that plenty of active additive was left in
this fill. 1.0 is too low for extended use. Try running
7,000 miles next time.
