What is the freezing point of gasoline?

Gasoline does not freeze; ice is the solid state of water, not gasoline. Theoretically, the freezing point of gasoline is -60°C, but different types of gasoline have different compositions, resulting in varying freezing points. In daily life, there is no need to worry about gasoline freezing because residential environments do not experience such low temperatures. Here are some methods for choosing gasoline: 1. The most important factor is to select the appropriate gasoline grade for your car based on the engine's compression ratio. Engines with a high compression ratio should use gasoline with a higher grade (i.e., higher octane number), while engines with a low compression ratio should use gasoline with a lower grade (i.e., lower octane number). 2. For a compression ratio of 7.5~8.0, use 90-octane gasoline; for a compression ratio of 8.0~8.5, use 90~93-octane gasoline; for a compression ratio of 8.5~9.5, use 93~97-octane gasoline; and for a compression ratio of 9.5~10.5, use 97-octane or higher-grade gasoline.
