Can lighter fluid freeze

Yes.

Everything freezes.

The universe would freeze and obliterate itself if it got down to 0K (Kelvin)

How exactly would the universe obliterate itself if it reached 0 Kelvin? I don't think you understand heat transmission in a vacuum. Additionally if the entire universe had a collective temp of 0 Kelvin then it would have to assume that all matter was evenly separated, that there were no black holes and that the universe has stopped expansion and was neither retracting but just static. Even then though the universe being at 0 kelvin would not be what killed it but a result of being dead. When you evaluate matter in all its forms you can see how preposterous that statement is or to put it another way:

No where in your rambling incoherent response did you come close to making a rational thought, everyone here is now dumber for having read it, I award you no points and may God have mercy on your soul.

PS, with enough pressure everything does not freeze but lighter fluid in normal circumstances will freeze at -220 F. The thing though is at what temp is it still useable? depends on your heat source, as you still need to raise it's temp to its flash point, so at a cold enough temp you may get it to spark but not remain on fire due to the temp of the liquid. Ronson light fluid has a flash point of 4c.
