What happens if you suddenly switch from 95 to 92 octane gasoline?

[CharlesLee]

95 suddenly switching to 92 octane gasoline can cause certain damage to the car's engine, and in severe cases, may lead to engine failure. 95 octane gasoline has higher anti-knock properties than 92 octane but lower than 97 octane. Gasoline can be categorized into different types based on its source: straight-run gasoline, catalytic cracked gasoline, thermal cracked gasoline, reformed gasoline, coker gasoline, alkylate gasoline, isomerate gasoline, aromatized gasoline, etherified gasoline, and polymerized gasoline. The working principle of the gasoline supply system is as follows: the fuel pump draws diesel from the fuel tank, filters out impurities through the filter, and then enters the low-pressure oil chamber of the injection pump. After increasing the fuel pressure, it is delivered to the injector through the high-pressure fuel pipe. The injector sprays the fuel into the combustion chamber in a mist form, forming a mixture that burns and performs work, and then the exhaust gas is discharged into the atmosphere through the exhaust system.
