Blackstone comments: Sorry for the confusion on your last report. We've updated your file. Copper is still the only metal reading in excess in this new-to-you engine, and it has come down nicely. Although we don't know why it was high in the first sample, the fact that it's improving is a good sign that it's not going to be a long-term issue for this Tacoma. The TBN read 2.3, showing active additive still remained in the oil. No fuel, antifreeze, or water was present. Air and oil filtration are normal. This engine looks good! You could try 12,000 miles next time, if you want.

Blackstone messed up the vehicle in the last report, hence the apology. My concern was the copper and it's coming down. Wondering why it was so high. I think I'm going to run a couple more oil changes and sample again.
