Not true. Think about the phase diagram. At temperatures above the

liquid.

Triple point is -190C

Apologies. I may have meant critical temperature. But you seem to have
understood what I meant (below).

A quick calc suggests that the gas will compress to the same density
as the liquid at about 300bar (needs checking). Keep your pressure
above this and you would see no difference.

.... and 300 bar isn't an unreasonable pressure for an injection
system. Many modern diesels run at roughly ten times this pressure.

I sound like I know what I'm talking about, but don't
be fooled.
