My first extended drain. Not quite sure what to think. Compared to the other samples there are some interesting trends.

The relatively high iron (compared to the trop artic) is interesting. but what is more interesting is that on a per 1,000 miles basis the iron level is about the same as it was with the Napa 5w20. Why I find this interesting is that these were both winter time OCI's and the silicon levels are remarkably similar. The trop artic sample was all highway summertime miles with a different brand of air filter and much lower SI.
the aluminum was still quite a bit lower than the NAPA which for this motor could mean less wear on the top end -- which would be quite good.
The TBN is outstanding for that mileage, but this would represent one quart of Edge black, and 2 quarts of Edge gold for top off in the 10k oci.
surprised at the viscosity, though. I would have thought that the Castrol would have held on to the viscosity a little better.
surprised at the copper and lead. but with more miles, maybe those numbers aren't concerning.
What do you guys think about running 10,000 miles on an OCI during the winter?
I'm still new at this so help me out.
Oh, this was with a Bosch D+ oil filter.
Current fill is the same oil for same OCI and Fram Ultra filter.
