Sorry, no VOA of this batch. I put TGMO 0W-20 back in for another 5K OCI.

Does the SR5 have an engine oil cooler? Looking for a source for the copper reading.

My copper reading was high at 10k miles too (44) but came down quite a bit by 25k (12) I think it may just be normal for these engines as they break in.

Don't worry about it too much, and do another UOA later to see if it comes down.
