Can a car that requires 95 octane use 92 octane gasoline?

[TuckerAnn]

It is not recommended for long-term use. If you accidentally use or mix different octane gasoline for a short period, generally no special maintenance is required for the vehicle. However, if a car that normally uses 95 octane gasoline is filled with 92 octane, it is advised to use up the gasoline and then refill with 95 octane. Here is additional information: 1. Composition: 92 and 95 octane gasoline: 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. The higher the proportion of isooctane, the better the anti-knock performance. 2. Avoid long-term mixing: Gasoline is a mixture. Although mixing or using the wrong octane once or twice is not a major issue, it is absolutely not advisable to mix them for a long time. To ensure the safety and performance of the vehicle, it is best to clearly distinguish the octane ratings before refueling. Otherwise, it will directly affect the engine, shorten the lifespan of the spark plugs, and lead to more exhaust pollution.
