Exactly, if I wanted a heavy 5W20, I would probably end up getting a light 5W30.
Look at the KV100 Viscosity
M1 5W20 = 8.9 cSt (ILSAC)
M1 5W30 = 11 cSt (ILSAC)
Edge 5W30 A3/B4 = 12.0 cSt (Euro oil)
The above seem fairly typical to me, but I find Pennzoil Platimum fairly light for its grade
PP 5W30 = 10.3 cSt
Rounding viscosity to the nearest whole number you get: 9, 10, 11, 12 cSt above. Take your pick.
