Moms new 08 RAV4 on dealer bulk Syntec blend, I was told it was syntec later found out it was blend. oil boy wasn't too happy about filling the bottle. got the what do you need that for.
anyway here it is.thoughts, comments........
going to keep it on the dealer recommended 5K OCI for now will pull another sample at 20K. the way mom drives that shouldn't take too long.
also have to see if dealer stocks full synth for after break-in.
5k max is Toyota's recommendation.
This engine throws off serious copper for 25k miles.
In NYC, because of the driving style and weather patterns, I would definitely stick with a full synthetic.

That right there probably accounts for a substantial portion of your silicon reading. I seriously doubt he took any steps to ensure he was collecting a clean sample.
