"... There is a newer Glycol Ester DOT5 ..."

I think you're referring to 'DoT5.1'  I also think it was deliberately 
named so as to confuse the issue.

      Also everyone is speaking of DOT5 but there are now two different
      DOT5s. The first is the older silicone based DOT5. There is a
      newer Glycol Ester DOT5 that is compatible with DOT3 and DOT4. It
      has a lower viscosity than the DOT3 and DOT4 so it works better in
      some ABS systems. It also has a higher boiling point than DOT3 and
