Pennzoil Platinum 10w-30
100 degrees, cst 10.5
Low Temp, cP 4570 @ -30
Valvoline Maxlife 5w-30

Low Temp, cP 5800 @ -30
Valvoline Maxlife 5w-30

I knew that Maxlife was "thicker" when compared to non-high mileage oil and was also expecting GC to the "thick."
What surprised me was the cP of GC 0w-30 compared to PP 5w-30. Is the GC not as super duper as I thought? I was expecting it to be both the thickest and the thinnest of the bunch.
