Which type of gasoline is more flammable than ordinary gasoline?

High octane aviation gasoline is designed for high-performance aircraft engines which require a fuel that can sustain higher compression ratios without knocking. This type of gasoline typically has a lower flash point and is formulated to ignite more quickly and easily than regular automotive gasoline.

The unique properties of high octane aviation fuel make it significantly more flammable, which is essential for meeting the demands of aviation operations. Regular automotive gasoline, in contrast, has a higher flash point, making it less volatile under the same conditions.

Diesel fuel and kerosene both have higher flash points than aviation gasoline. Diesel fuel, commonly used in industrial and heavy-duty vehicles, is designed to be less flammable to ensure safer handling and storage. Kerosene, known for its use in jet engines and heating, also has a flash point that is significantly higher compared to high octane aviation gasoline. Thus, these fuels are inherently less flammable than aviation gasoline, which is why they do not match its combustibility.
