Which fluid properties matter for procurement?
Compare viscosity at 40°C and flash point by the same test method. Lower viscosity moves heat faster; a higher flash point gives more margin. Shell S3 X runs 9.9 cSt with a 198°C flash point; ExxonMobil EM DC 3235 Super runs 14.3 cSt and 234°C. For two-phase, the boiling point sets the operating temperature.
