Well, none of the VOAs show any significant Fe. An example:

Maybe it has something to do with a heat-activated additive? I honestly don't know. I'm not an oil expert, I'm a Network Engineer. But in the (admittedly limited) experience I have with the results of using M1, I have never observed WEAR as being an issue. So despite the high-iron claims, what I have actually seen has been NOTHING. And these are high mileage engines.
I used M1 for years. It was my standard choice before finding BITOG and I always felt I was doing the best for my engines. Obviously I never had a problem either, but when would you expect to find one? I just figure that half the PPMs probably equals half the wear, more or less, and half the wear probably equals twice the remaining life, more or less.
Not saying M1 has double the PPMs, of course.
