i think this is the best way to measure it, take a bottle of the fluid off of tower hobbies and watch it drain through a funnel and record its time, then try to get my silicone of the same quantity to drain in the same time meaning a similar viscosity.
If you buy the fluid from Tower, you could just use the fluid instead of running tests on it. Chances are you would never finish the bottle, so finding a substitute would not be necessary.
Somebody's signature summed it up best when they said something along the lines of:
"If Wile E. Coyote could afford all of that ACME crap to catch/kill the roadrunner, why didn't he just buy dinner?"
In other words, why go off on a quest that will cost you more (both time and money) than just buying the fluid in the first place?
