The current Falcon 9 version "chills" its RP-1 as well (so they can fit more in the same tank volume). It's not far below 0 degrees Celcius, though.
What's more interesting is that the oxygen is also cooled below its boiling point to make it denser (so they can fit more in the same tank volume).
(PS: there are two propellants but only one of them is called "fuel". The other one is the oxidizer.)
