What is the freezing point of gasoline?

[LeWyatt]

Typically, the freezing point of regular gasoline is minus seventy-five degrees, while pure ethanol gasoline has a freezing point of minus one hundred and seventeen degrees. The concept, composition, and selection criteria of gasoline grades are as follows: Concept of gasoline grades: It refers to the ratio of the actual anti-knock performance of gasoline to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Composition of gasoline: Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, with an octane rating of 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with an octane rating of 0. Selection criteria for gasoline grades: The primary criterion for selecting gasoline grades for a car is the engine's compression ratio, which is also a core energy-saving indicator of modern cars.
