Well i just found where to buy silicone oil in bulk, dow corning the company that you see on those tubes of rtv and stuff.... they make a MASSIVE variety of every silicone substance you can think of, the units are sold by the gallon for 35, a five gallon bucket for 165 or a 55 gallon drum for 1000 something.

i am first going to buy the gallon can of a thicker oil to be the base, then just take small bottles and dilude them to a thinner viscosity and try it out maybe it will work. at the same time i am ordering some oil from tower hobbies to compare.

the only thing i am completely stumped on is how in the hell does a person measure viscosity of a fluid....

the silicone oil everyone uses will blend with other silicone oil right? i think i read that somewhere
It's actually pretty simple. You measure the time it takes for a specific volume of fluid to flow through a funnel with a (to me unknown) hole.
Do a google search of viscosity and you'll see alot of info.
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.
