Hydrophobia is not a detraction of DOT 5, but a benefit. Can someone site an
example of definitive research showing that water will pool in silicone? I don't
think so! Try leaving some in an open graduated cylinder for a year or two and
see if the volume changes, or any pools of water show up.

Compressibility? Of a liquid? If such a thing could occur, I seriously doubt one
could detect it with a foot.

I respectfully suggest this is a myth. If the stuff is no good I'd appreciate
some proof before I remove what appears to be perfectly performing, 10 year old,
anhydrous brake/clutch fluid, and replace it with rust-worm food.
