Jet aviation fuel is typically kerosene, which has an average carbon chain length of about 10, as compared to diesel which ranges from 12 to 15. Among critical factors, diesel fuel freezes at far higher temperatures than kerosene, which is important for both aircraft (which typically fly in ambient temperatures about -40 °F/°C) and polar operations. Blends such as Jet A1 and Jet B (kerosene + petrol) have still lower freezing points of -47 °C and -60 °C respectively. Diesel's freezing temperatures are ~ - 8--9 °C / 15--17 °F. Kerosene and jet aviation fuel are rated to -40 °C / -40 °F (both temperature scales are the same at this temperature). Piston aircraft burn petrol / gasoline with a freezing point of ~ -73 °C / -100 °F. Shorter hydrocarbon chain lengths -> lower freezing temperatures. Methane (CH4) is liquid to -182 °C / -195 °F, and only liquifies at -162 °C / -259 °F. <https://www.amspecgroup.com/news/types-of-jet-fuel/ https://www.amspecgroup.com/news/types-of-jet-fuel/>
