Huh? The test isn't applicable to synthetic oil? OK, whatever. It
matters not, though, because until ~1992, M1 wasn't 100% synthetic.
Also, somehow Amsoil managed to get the first API certification of a
100% synthetic in about 1975. Did they cheat?

With all due respect, tell me with a straight face that you'd move back
to Wisconsin and use 30 weight petro oil in the winter. This synth
bashing is getting a little tiresome. M1 10W-30 has a pour point of -55
dF. The 10W-30 I use has a pour point of -75 dF. Is this an advantage?
If it means the oil pumps quicker on startup to the engine in my race
car/boat towing/cross-country trip taking/161k 1987 4000CS quattro, YOU
BET! If regular 10W-30 petroleum oil has a pour point (guessing here) of
-35 dF, do M1 and my oil have an advantage? It seems pretty clear from
here . . .

BTW, my engine seems immune to the leakdown stuff yours suffers from.
Even at 161k original, I can start up at 0 dF with nary a tick from a
bearing or a lifter. I guess Audi, who requires synth in gearboxes and
is compelled to pay for it during "Advantage" service is just wasting a
little of Ferdinand's pocket change. The synth bashing is getting a
little tiresome.

Based on the fact that it wasn't 100% synthetic, I'm skeptical.
