I tried this, i cant see any obvious viscosity by shaking etc.
Did you mix the HyperLube Zinc replacement with QSUD and then put it in a freezer?
You lost me in your sequence of events and what you used.
I took a bottle of qsud and took out 2.5 oz of oil, added 2.5 of the zinc replacement. I shook it well , no noticeable difference. I set it on my porch overnight with another unopened bottle of gsud (20f overnight. I could not see a real difference, so i then put both bottles in the freezer for several hours at say -8. I took them out, shook them looked at how the oil moved, ran down the neck of the bottle, looked at how the air bubbles moved through the cold oil when shaken. Not sure what i should have seen but i could not really tell a difference. Did i use enough of the additive? This oil is going in my saturn tomorrow btw.
Okay, gotcha.
You should see little difference between the unadditized oil and the additized oil in terms of low temp viscosity, which appears to prove what I said earlier.

It should not matter.
