The bottles say CPS, I think they mean WT though, but I might be mistaken.
So the last one has the highest viscosity.
That said; forum members recommend 30,000WT/ 50,000WT silicone oil. The bottles on that site say 30,000CPS and 50,000CPS.
According to this converter, 30,000WT is 1,250,461CPS which would give 30,000WT the viscosity of a brick according to this. It says "Lard has a viscosity of a whopping 100,000 centipoise".
I have/ use this stuff, which is far from being a solid and is measured in WT.
EDIT
Ah, on the last site I posted it says #30000 in brackets. On the site you posted it also says #30000, so I guess it's the same viscosity
