Here are two cuts from the site:
"DOT 5 is for silicone brake fluid. Silicone brake fluid (DOT 5) should be avoided because it is not compatible with regular brake fluid, it is hard to pour without introducing bubbles and thus results in soft pedal feel, and moisture still gets into your system and will pool in low areas like your calipers and encourage rapid corrosion. STAY AWAY!"
"That leaves DOT 3 and DOT 4 fluids. These fluids are compatible with each other and may be interchanged or mixed with no ill effects."
My comment: A thing to consider is that different makes absorbs moisture in different degree. Some of them quick and other slow (see the site above). Hey, it is a jungle out there!!!
