At what temperature below zero does 92-octane gasoline freeze?

[Nelson]

92-octane gasoline has a freezing point of -75 degrees Celsius. Introduction to 92-octane gasoline: 92-octane gasoline is a type of gasoline with an octane rating of 92 and a heptane rating of 8, suitable for mid-range vehicles. On December 18, 2013, the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of China jointly issued the fifth-phase national standard for automotive gasoline — "Automotive Gasoline". Introduction to gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid and is flammable. Gasoline is a mixture and does not have a fixed freezing point; the freezing point varies with different octane ratings. The general freezing point of gasoline is -75 degrees Celsius.

As a car enthusiast, I often study fuel properties. The freezing temperature of 92-octane gasoline is generally below -40°C, depending on additives and climate. In normal winter conditions in mainland China, such as the Northeast where temperatures can drop below -30°C, gasoline doesn’t freeze because it’s a mixture of hydrocarbons, unlike water which freezes easily. More common issues in cold weather are reduced fluidity or clogged fuel lines, which can affect engine starting. It’s advisable to use winter-blend gasoline or add antifreeze in cold regions and keep the fuel tank full to minimize condensation risks. In extreme cold like -50°C, gasoline might freeze, but at such temperatures, the car battery would fail first. So, daily concerns are minimal; the focus should be on regular vehicle maintenance.

Having driven for over 30 years, I've accumulated considerable experience. No. 92 gasoline only begins to freeze at around -40°C, which is rarely encountered in cities. I remember one year when I was traveling in Mohe, with temperatures at -35°C, the car was hard to start not because the gasoline froze, but because the filter was clogged with cold wax. Gasoline itself has a very low freezing point, below -40°C, and the antifreeze properties of additives are crucial. In daily life, just pay more attention to warming up the vehicle and using high-quality fuel, and avoid mixing water or impurities into the fuel tank. Instead, focus on the air conditioning system and tires, and don't make a mountain out of a molehill.

Considering family travel safety, I'm particularly concerned about gasoline freezing issues. Research indicates that the freezing point of 92-octane gasoline typically ranges between -40°C to -50°C, occurring only in extremely cold weather. However, in places like Beijing where temperatures rarely drop below -15°C, this isn't a concern. In the unlikely event of extremely low temperatures, gasoline may partially crystallize or experience reduced fluidity, potentially causing fuel pump failure. As a preventive measure, I make it a habit to keep the fuel tank warm in the garage and use fuel from reputable gas stations to ensure purity. More realistic risks include frozen windows or brake failure, for which having de-icing tools on hand provides sufficient peace of mind.
