Should the 2021 Levin use 92 or 95 octane gasoline?

[StKeegan]

Both 92 and 95 octane gasoline can be used, but it is best to consistently use one type. There is not much difference between 92 and 95 octane gasoline in essence; the only difference lies in the octane rating. 95 octane gasoline consists of 95% isooctane and 5% n-heptane, while 92 octane gasoline consists of 92% isooctane and 8% n-heptane. Below are some related points: 1. Gasoline octane rating: The gasoline octane ratings that car owners see actually refer to the ratio of the gasoline's anti-knock properties compared to standard gasoline. For example, 95 octane gasoline indicates that its anti-knock properties are the same as those of standard gasoline containing 95% isooctane and 5% n-heptane. This does not mean that the 95 octane gasoline used in daily life contains 95% octane. 2. Higher octane does not mean better quality: Additionally, a higher octane rating only indicates better anti-knock properties and does not mean the gasoline is of higher quality. There is also no experimental proof that it improves the cleaning properties of gasoline. Moreover, the vehicle manuals specify which type of gasoline is suitable for each model. It is best for car owners not to mix different types of gasoline to avoid causing engine knocking.
