Ethane is 18 W/mK ingame. Not sure if this is supposed to be for a gas or liquid, but given the application as a high temperature coolant a value representing it as a gas seems appropriate.

Oxygen is 8 W/mK ingame. Same thing as above.

Suggested replacement values (well, in the right ballpark) from here:

Ethane: 0.021 W/mK
Oxygen: 0.026 W/mK

Really, what would be ideal would be a rigorous treatment, using the thermodynamic conditions in order to calculate the appropriate properties. But at the very least, automatically using the right properties for the three different possible regimes - liquid, gas and supercritical fluid - should be implemented.
