Copper and lead traditionally show bearing wear and lead at 40 ppm shows a lot of it. Copper can also be
from any other brass/bronze parts. You mentioned changing the air filter. Silicon is quite high here, so maybe
some abrasive dirt was getting into the engine. That might explain the metal, but there could be a problem
here too. No fuel showed up. The TBN shows a little active additive left at 1.5, but try just 3,000 miles on the
next oil and resample.
This is a sample from my 2002 Buick Century. Fill was Pennzoil Platinum 5w30 API SN + a older Made in the USA K&N HP-1001 oil filter w/filtermag.
Previous air filter was a K&N air filter and very shortly after changing the oil i went to change the air filter and the gasket was trashed and the filter was collapsed letting dirt into the engine the whole time. I am guessing there was a lot of abrasive dirt in the engine from the entire time the K&N was letting unfiltered air in the engine.

I used techron 3 times during this fill, had very high idle time in the cold sometimes 4-5 hours a week. Not sure if the techron leached lead out like i have heard before? I sure wish the lead was from something else.
The engine consumes zero oil, and the 0.6 quarts i added for top up were just the leftovers from the 5.1 quart jug i had since the engine only takes 4.5 with a oil change and i dumped that in probably halfway through the oci.
Right now it has the whole PU 5.1 quart jug in there with an oversize Fram XG filter.
I am going to start doing shorter changes in the future and monitor the lead. I have seen high iron/high copper GM engines last awhile but not with high lead. I saw a light amount of copper glitter in the bottom of the oil pan when i drained it.
I can still see the Ti from the last fill of Kendall GT1. Interesting to see the TBN so low after only 5,700 miles with the extra half a quart i threw in there halfway through the OCI.
