Driving at -30 Celsius versus driving at +25 Celsius. The gasoline has less kinetic energy at -30 Celsius... Yet our cars run fine at -30. You would think that there would be a massive difference because 60 degrees celsius difference (-30 vs +30) is a LOT of kinetic energy. Most problems in the winter have to do with thick oil in the engine, and ice in the gas tank from water. Gasoline temp itself doesn't seem to be a problem in the winter. Atomizing the gas is indeed sometimes a problem, but atomization is good enough to ignite even at -30. So if you had really cold gas at -50 celisius and you could ignite it, that would contain less kinetic energy initially, but once out the tail pipe... it seems to run the engine generally the same? WTF? It's not like the engine fails to run due to that massive loss of initial kinetic energy of the gas.
