[DeTomaso] New Castrol GT LMA Brake Fuid

[jefude at bellsouth.net]

Time for my annual fluid changes. I have used Castrol GT LMA for years in the clutch fluid system.
 
This year the Castrol container says” New formula” and” Synthetic “.  I do not have any of the old product. Was it also synthetic? I am concerned about mixing fluid types and how that may affect the master/slave seals.
