Does gasoline evaporate in hot weather?

[Lane]

Gasoline evaporates regardless of whether it's cold or hot, but it evaporates faster in hot weather compared to cold weather. Here is some relevant information about gasoline: 1. Gasoline octane rating: The octane rating represents the anti-knock property. A higher octane number indicates better anti-knock performance, but it has no relation to the quality of the gasoline itself. A higher octane rating does not mean the gasoline has fewer impurities. 2. Unleaded gasoline: The common unleaded gasoline available in the market includes 90, 93, and 97 octane. In major cities, Sinopec also supplies high-clean 90, 93, and 97 octane unleaded gasoline, which not only has lower lead content but also contains small amounts of additives to clean the fuel system.
