*While we have only listed Motul RBF600, RBF660 and a few others, the performance characteristics are applicable to a large number of other brands of fluids as they all come from mostly one manufacturer.  

**When extreme boiling point values are unavailable from other brake fluids, their ERBP or known standard boiling point value that is publicized will be used.
