Blackstone comments:
Your extended your oil use and copper decreased and it may be that it will finally settle down
to average levels. Copper from brass/bronze parts usually takes its sweet time to reach normal levels
and we think it is finally there at 47,226 total miles. All of the wear metals read very close to or below
the universal averages for this type of engine. The TBN was 2.6, some active additive left in the oil. No
contaminants were found and air and oil filtration were normal. All in all, a very good report as of
6/16/07, the sample date. Nice wearing BMW!

Copper is finally down, no drivers schools or Auto X events on this OCI.

Nice report! I'm running GC in mine now too. Will have it analyzed at 5k.

You ran BMW 0w-30 oil previously? Which oil is that? I thought the BMW High Performance oil was 5w-30.

 

[shanneba]

The BMW oil runs were both 5w-30. Free changes from the dealer. Maybe the BMW filter with GC had you thinking it was BMW 0w-30?

 

[Quattro Pete]

Oh, I see now. The columns aren't lined up properly on my monitor - the word BMW shows directly above 0w-30, hence my confusion. Nevermind.
