Seems my previous message on this topic didn’t appear on FoT.  An edited version is below.  Has nobody else here tried DOT 5.1?

It is polyethylene glycol-based (it must be less than 70% silicone by definition) so it’s compatible with DOT 4 but it is not so easy to find these days.  It’s a bit less viscous than DOT 3 or DOT 4, same viscosity as DOT 5.
