That makes great sense.
I guess I was thinking that this would be a great tool for when you are
thinking about buying a car (or mower, or other engine.) If it worked, it
would be a quick way to tell if the owner took care of it.
So the question then is, could it work for that?

Amen. On the cars, I do 3,000-mile (or annual on the MG and Model T) oil
changes, despite running synthetic in the Mustang and Yukon. I doubt that
this would show that the oil I'm throwing out is bad.
I change the Stearman's oil (4-1/2 gallons at a time) based on running
time
and season. Because of seasonal changes, I seldom approach the very
conservative 25-hour spec that applies but was set in the 1930's, but
still
send samples to Blackstone every time. They send more than a full sheet
of
data, which I correlate to my recent maintenance and use/storage pattern
to
make sure it looks right.
A simple good/sorta good/bad display doesn't tell you much about the
identity of various particulates, like how much iron, tin, lead, aluminum,
zinc, carbon, etc., so it's NOT a substitute for actual oil analysis. Is
it
better than not testing at all? Maybe, but I don't want to wait to change
oil till I see a "bad" reading.

Sounds awesome, but also like snake oil.
I send samples to Blackstone Labs for analysis. For $40, sounds like
sub-harbor-freight garbage I wouldn't trust further than I could throw it.
