Is it harmful for a car designed for 92 gasoline to use 95 gasoline?

[Nascimento]

There is an impact. Long-term use of 95 gasoline in a car designed for 92 gasoline can cause damage to the vehicle. Gasoline octane rating: It represents the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane number, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane numbers are not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. Precautions for gasoline use: Gasoline is somewhat toxic, so avoid sucking gasoline with your mouth and try to avoid inhaling gasoline vapors. Pay attention to the quality changes of gasoline during long-term storage, especially to prevent it from aging. In high-temperature summer regions, vapor lock may occur while driving. It is necessary to enhance engine cooling and ventilation, and if needed, insulation or water dripping measures can be applied to the fuel pump and fuel inlet pipe to reduce temperature.
