DOT 5 fluid has much higher dry and wet boiling points, but it has
some problems - not the least of which being compressibility that
varies with temperature and altitude.  The only reason to use DOT 5
is this - it doesn't eat paint like DOT 3/4 does.  See this URL for
a better explanation:

It's not hard to get DOT 3/4 fluid that performs perfectly well - I
use Castrol GTLMA; if you really want something serious, get the Ford
heavy duty stuff - it's just repackaged Castrol racing stuff (I might
be able to find a PN# if people want it).
