I came across this product on the QS site, Winter Syn Blend Motor Oil. The specs look unusual:
cSt @ 40C 49.89
cSt @ 100C 10.5
VI 207
CCV -35C 3750
CCV -40C 15000
Low temp pumping vis -35C cP 8100
Low temp pumping vis -40C cP 15000
Product Data Sheet
So, my simple logic would infer that they're starting with a light base oil, possibly adding some PAO - and alot of VII.
I just wonder about HT/HS, and rate of shear?
