 OK>>>OK
I just got off the phone with Valvoline.  They say it is the same as DOT3 and DOT4 only better.  They woudn't tell me what the synthetic is, but that is what makes it better and work for both DOT3 and DOT4 and work at higher temperatures.
They say it has no negative effects on seals, older or newer.
