What fuel type is specifically blended to operate in extremely low temperatures?

Jet B is a fuel type specifically blended for use in extremely low temperatures. This kerosene-based fuel has a lower freezing point compared to Jet A, making it suitable for operations in very cold climates, such as those encountered by aircraft flying at high altitudes or during winter operations. Jet B is a blend of kerosene and gasoline, which gives it the necessary properties to prevent gelling or freezing under harsh conditions.

In contrast, Jet A, while commonly used and capable of performing well in a range of temperatures, does not have the same low-temperature performance characteristics as Jet B. Aviation gasoline is used primarily in piston-engine aircraft and is not designed for jet engine operation, thus making it unsuitable for this context. Diesel fuels, on the other hand, are designed for compression ignition engines and do not compete with aviation fuels in terms of low-temperature performance for jet engines.
