Oh Pablo.
Did nothing…Then you did not follow direction, do not test correctly or you can’t read UOA! LOL
The dreaded if no one likes amsoil…Amsoil is not the best hands down…oil is good, very good but not the best…sorry
Again LC20 really makes amsoil much better. After 15 years of using amsoil, lc20 makes it able to do what amsoil states it can do alone.
That being stated, you said “I've looked at a LOT of UOA's and say maybe, just maybe LC kept oil on the thin side, perhaps via oxidation reduction (speculation)”. A lot of speculation you posted and you have the test numbers in front of you?
I posted on it before but…..
Anything Negative means gone down or is what you LIKE or want. It (-) is a good thing. It is being compared to oil (Amsoil ASL- past tests) running nothing.
Iron Dropped: (-)54.54%....(-) 16%
Lead
-) 59%...(-) 10%
Copper: (-)54.54%...(-)37%
Tin: 0%...(-) 100%..same
Alu: 0%...(-) 50%..same
Nickel: 0%..0%
Silicon: (-) 1%...UP 29% (expect that due to RTV on valve cover)
Boron: (UP) 5%...(-) 100%
Sodium: (-) 100%....(-) 100%
Magnesium: (UP) 2%...UP 7.8%
Cal: (-) 29.2%.......UP 8.2%
Phos: (-) 11.9%...(-)3.39
Zinc: (-) 8.29%...(-)6.24%
Moly: 0%...0%

OXD

NOX

All these are in my engine, that eats amsoil up pretty good.
So I do like Amsoil but LC20 in the oil makes it able to achieve better results then running amsoil alone. The more I learn about of items on this forum, the more and more I find myself going in the opposite direction of the dreaded MLM hype and "$40 per year dealers".
