I was a little skeptical about the "Extra Anti-Wear Protection," so I looked on the MB1 website and found that 0w-40 does in fact have just a little more Zinc/Phos additive, which is a common additive for reduced wear.
Also, it's spec'd for BMW & Mercedes (Normally calls for 5w-30; 0w-40 is rec. when using MB1) and GT-R etc...
As for "better flow," I think it's b/c it's a 0w weight oil.
