That's just not true. It's true in certain engines and situations - with some synthetic oils there will be elevated Cu. For Fe, the statement doesn't play any better than M1 shows high Fe in gasoline engines.
What's "not true" about the high Fe and Cu in Amsoil UOAs?
When I say "well documented", I'm talking about UOAs with ppm counts for Fe and/or Cu that exceed the typical (commonly called universal) averages. You simply cannot say that there are not UOAs out there that do not support this fact. My statement is truthful when read without bias.
"High Fe and Cu in Amsoil UOAs is well documented ..."
How's that not true?
Here's a small sample with different engines and circumstances, but the commonality is Amsoil brand lubes of different grades:

I never said it happens in all Amsoil UOAs. There are many Amsoil UOAs where this phenomenon does not occur. I also certainly stated it happens with other brands. But CLEARLY we can see that it's "well documented" that Amsoil UOAs can at times, present proof that "high" Cu and/or Fe exist on a "per mile" basis when viewed against universal averages.
I've seen many Amsoil UOAs that were outstanding, and very impressive. They typically are from people who are dedicated to UOAs and not the odometer. They typically are from people who use Amsoil religiously, with a good understanding of the phenomenons associated with it's use.
To be honest, I really don't even understand the dichotomy of your statement:
"
That's just not true. It's true in certain engines and situations ..."
What the heck does that mean, Pablo? It's not true, but it's true ...? That's about as contradictory as one can be in one's own statements, with two sentences back-to-back.
Let's let people read the UOAs and make up their own minds.
I was merely trying to point out that the post from LouieLouie was implying that a lighter grade oil was the cause of the high Cu and Fe, and it's MUCH more likely that the cause is the Amsoil chemistry. Nothing more, nothing less.
