That's because it isn't silicone like DOT5, but glycol based like DOT3, 4
and 5.1.
Silicone not being hygroscopic is not relevant as a hydraulic system will
absorb moisture regardless of the fluid used, which is why silicone has dry
and wet boiling points quoted the same as non-silicone, and the wet is the
same percentage lower than the dry as for non-silicone fluids
(http://en.wikipedia.org/wiki/DOT_5).
The temperatures quoted by Castrol should read 310 F to 329 F (155 C to 169
C) of course :o) However they are the wet boiling points and not the dry,
see
http://www.castrol.com/liveassets/bp_internet/castrol/castrol_usa/STAGING/local_assets/downloads/p,q/pds_GTLMABrakeFluid.pdf
which quotes 509F/265C dry and 311F/155C wet.
