I will say I've had my oil analyzed four times on my ZL1 at each oil change, the most recent at 9800 miles and the metal wear was the lowest it's been yet.

That's great to know about your oil analysis being the lowest.
I did think about sending the oil to have it analyzied, after I dumped it in my drain bucket lol. I'll do the next one.
