DOT 3-4 series fluids are alchohol based products and what most
vehicles use in their systems.  DOT 5 series is silicone based and is
only used in SOME vehicles.  You CANNOT mix the two or serious damage to
your brake system will result.  There is some benefit to the DOT 5 as it
does not contaminate as quickly and therefore is more desireable.
However it is a relativley major project to change over to the DOT 5
from DOT 3-4.  All rubber components must be replaced and the system
must be thoroughly flushed.  Hope this helps.
