As an expert in the field of fuel science and engineering, I've spent years studying the properties and behaviors of various types of fuels, including gasoline. Let's delve into the intricacies of whether fuel can freeze and the factors that influence this phenomenon.
First and foremost, it's essential to understand that gasoline, like many other liquids, has a freezing point. However, the freezing point of gasoline is not a fixed value but rather a range, typically between -75°F to -40°F (-60°C to -40°C). This variation is due to the composition of gasoline, which is a mixture of hydrocarbons with different molecular structures and properties. The freezing point of a substance is the temperature at which it transitions from a liquid to a solid state, and for gasoline, this transition is influenced by its specific components.
Now, let's address the statement that alcohol absorbs water and its implications for gasoline. Modern gasoline often contains ethanol, a type of alcohol, which is added to improve octane ratings and reduce emissions. Ethanol does indeed have a hygroscopic nature, meaning it can absorb water from the environment. When gasoline contains ethanol, it can absorb moisture from the air, which can lead to the formation of ice crystals at temperatures above the freezing point of pure gasoline. This is because the presence of water lowers the freezing point of the mixture, a phenomenon known as freezing point depression.
The concern about a half tank of fuel collecting moisture from the atmosphere is valid. Over time, as the fuel sits in the tank, it can absorb moisture, which can lead to a decrease in performance. This is particularly true in colder climates or during the winter months when the ambient temperature is closer to the freezing point of the fuel mixture. The moisture can cause the formation of ice crystals within the fuel, which can clog fuel lines and injectors, leading to reduced engine performance or even engine failure.
It's also important to note that the freezing point of gasoline can be affected by other additives and contaminants. For example, some fuel treatments and stabilizers can alter the freezing point, either by reducing it or by preventing the formation of ice crystals. Additionally, the presence of other contaminants, such as dirt or rust particles, can also impact the freezing behavior of gasoline.
In conclusion, while gasoline can freeze, the presence of ethanol and other additives can complicate this process. The freezing point is not a single value but a range, and the actual freezing behavior of gasoline in a vehicle's tank can be influenced by a variety of factors, including the specific composition of the fuel, the presence of water and other contaminants, and the ambient temperature. To mitigate the risk of fuel freezing and the associated performance issues, it's advisable to use fuel treatments designed to lower the freezing point and prevent ice crystal formation, and to regularly check and maintain the fuel system.

Yes, but not so it doesn't freeze. Alcohol absorbs water so since most gasoline sold today is either 5% or 10% alcohol, you probably don't have much if any water in your tank. A half tank of fuel will collect moisture from the atmosphere and eventually your performance will suffer.Dec 23, 2010
