Car has 56k miles on it. I've only owned it for a month or so. Your thoughts would be greatly appreciated!

0 lead is a good thing!
May the road rise up to meet you, and your lead always be low.

Not necessarily. If you just installed fresh bearings, then yes, 0 lead is a great thing! But without that information, 0 lead with elevated copper could very well mean that the lead layer had worn away and probably already into copper. With a high iron reading on top of that, it may even be into steel...so I would be worried about bearings. These rod bearings are made of steel/copper/lead. Steel is an alloy, but most of it is iron. Just my opinion.

At 56k miles you would have had to flog her pretty hard to have that happen.
But I agree, insufficient information.

That's what I was thinking. Not sure what the previous owner did. Not sure how long the oil was in the car before I bought the car and changed it. The report states that it may have been a lower viscosity oil. We will see what another analysis says after 3k. Now using Motul 10w60 oil.

Mine was reasonably driven and maintained - you can see the condition of its bearings at roughly ~55K miles => https://www.zpost.com/forums/showthread.php?t=1461006

I still haven't done my bearings, yet, but I haven't driven the car in quite awhile, either. Been busy with other projects. Guess bearings will now be my spring project. I'd be worried with elevated copper.

Because of you, I have an appointment at the shop on 01/03/19 to have my rod bearings replaced, and I thank you!

Changed at 58k. Black stone analysis was on the money.

Why not? 0 lead with high copper meant you had already gone through your lead layer and into copper, which is exactly what your bearings are showing
