Its pretty easy to tell silicone from DOT 3 or 4. Silicone will be slick in your fingers, a blue/purple color, and have little odor. DOT3 and 4 stinks, is almost black when old, and feels like you really shouldn’t have stuck your fingers in it. It makes your fingers feel "squeaky" when you rub them together.

Don’t mix silicone with DOT 3 and 4. Gotta clean the whole system out first.
