Dowtherm MX provides long-term stability.

Dowtherm MX from Dow Chemical Co.provides long-term thermal stability and performance in zero-pressure, liquid-phase systems. Designed for application ranges of -10 to 625°F (-23 to 330°C), this synthetic aromatic-based heat transfer fluid does not experience thermal degradation and is pumpable to -10°F (-23°C). It is noncorrosive to common metals and alloys and has a high atmospheric boiling point of ~622°F (~328°C), making it a potential drop-in replacement for higher performing hot oils.
