KCJeep,
IMO, the new 0W16 grade, from what's been delivered by Ravenol, Citgo, and Penrite are (nearly) monogrades in their behaviour between low shear and high shear.
While I said that the 10W could REALLY (nearly) be labelled a 10W16, I wasn't joking that hard, it could be.
I think that the Japanese in pushing for these grades have lost the need for the stratospheric VIs, and poor high shear performance.
As to 10W, back in the early 1970s, the Bathurst race was won by a Holden Monaro with an SBC, running 10W with Bardhall additive.
