Should a V6 engine use 92 or 95 octane gasoline?

[StHarrison]

Whether a V6 engine should use 92 or 95 octane gasoline mainly depends on the driver's power requirements. Using 95 octane gasoline will result in greater engine power output. Each engine undergoes a comprehensive evaluation before leaving the factory, and based on performance data characteristics, the required anti-knock properties are determined, which dictates the appropriate gasoline octane rating. The differences between 92 and 95 octane gasoline mainly lie in their octane ratings, anti-knock properties, and prices. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline is composed of 95% isooctane and 5% n-heptane. Gasoline with higher octane ratings has greater anti-knock properties. 95 octane gasoline is more expensive than 92 octane because it contains a higher proportion of isooctane. Each engine undergoes a comprehensive evaluation before leaving the factory, and based on performance data characteristics, the required anti-knock properties are determined, which dictates the appropriate gasoline octane rating. Fuel usage precautions: Maintain consistent use of one type of gasoline; mixing different types is harmful to the engine and fuel system. The choice of gasoline octane rating should be based on the engine's compression ratio. Higher octane ratings are not necessarily better, and blindly using high-octane fuel is not advisable.
