How Cold Does It Have To Be For Fuel To Freeze?
The temperature at which fuel freezes depends on the type of fuel. For example, diesel fuel typically begins to gel or wax at temperatures between 15°F (-9°C) and 40°F (4°C), while gasoline can start to become thick and less fluid at temperatures around 32°F (0°C) or slightly lower. However, the addition of anti-gelling agents can help prevent fuel from freezing, allowing it to continue flowing smoothly in colder temperatures.
