high copper content in oil

I'm interested in knowing if any drivers have recently found high copper content in their oil analysis. Mine started about three months ago, with a reading of about 180 ppm.

 

I've talked to the mechanics, they seem to think that cat doesn't have copper on the bearings. I've also been told that it could be the oil cooler, air compressor, wrist pins. I heard recently that the oil has been changed to deal with the new motors and that cat in particular has all of a sudden shown copper in the oil, but that it runs its own course and decreases in a few months time. Any one hear anything like that or had a similar experience?

 

I didn't hear this first hand, but was told that a rep from gulf coast filters was on the Dave Nemo show, and discussed recent appearances of copper in the oil due to manufacturer's changes to oil to meet new standards. Did anyone catch that program, and remember more about it?

 

would anyone know if the air compressor could be a source of copper in the oil?

 

Thank you for the responses. I'm thinking that out of all the o/o out there, there are more than just two of us who have had copper in the oil. Any one else have a comment or some helpful information?
