This phenomenon happens when a fuel reaches a low enough temperature whereby enough wax crystals have formed to prevent any movement in the oil . For #2 diesel this is usually around 17.5 ° F (− 8.1 ° C). </P> <P> For the fuel to become pumpable again, it needs to be brought above the gel point temperature to the Ungel point, which is typically near its pour point . However, most of the waxes will still remain in solid form and the fuel has to be warmed up further until its Remix temperature in order to completely remelt and redissolve the waxes . </P>

At what temperature does diesel fuel start to jail
