at some point between the two values and not necessarily based on the proportion of each oil of the blend.
As you may well realise, an oil, in a blend is not a "constituent", it is a complete oil in it's own right, made up of a bunch of individual components...each of which is reduced in concentration by a half (in a 50:50 blend).
Do each of the additives perform linearly (and cumulatively) at 50% of the original treat rate ?
That is your (untested, yet again) assertion, and the reason that I raised it.
I note your statement that it's blending "their" various 0W oils, not randomly mixing someone else's oils.
Yes, I can see that if M1 use the same basic additive chemistry for all of their 0Ws, you end up with pretty much the same percentage of the same polymers, or a linear change in polymer/base-stock viscosity...it's reasonable to assume that you are somewhere in the middle.
Doesn't automatically lead (posit, assertion, or even assumption) that it is true when differing polymers are used
There you go again obfuscating your own ridiculous suggestion unapologetically attempting to high-jack this thread in the process.
Its a stretch to assume, as Shamwow has, that VI polymers would somehow cancel out or mutually interfere. Until someone shows this to be true, why raise this? Bring the evidence, or shut up. Throwing things out there doesn't cut it around here.
