Should the 2021 Levin use 92 or 95 octane?
2 Answers
Both 92 and 95 octane can be used, but it's best to stick with one type consistently. There isn't a significant 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 is made up of 92% isooctane and 8% n-heptane. Gasoline Octane Rating: The gasoline octane ratings seen by car owners actually refer to the ratio of the gasoline's anti-knock performance compared to standard gasoline. For example, 95 octane gasoline indicates that its anti-knock performance is the same as that of standard gasoline containing 95% isooctane and 5% n-heptane, as measured in research. This doesn't mean that the 95 octane gasoline used in daily life contains 95% octane. Higher Octane Doesn't Mean Better Quality: Additionally, a higher octane rating only indicates better anti-knock performance and doesn't necessarily mean the gasoline is of higher quality. There is also no experimental proof that it improves the cleaning properties of the gasoline. Moreover, each car owner's manual specifies the appropriate type of gasoline for their vehicle model. It's best not to mix different types of gasoline to avoid causing engine knocking or damage.
I've been driving a 2021 Leiling for almost two years, always using 92-octane gasoline without any issues. Toyota's engine design is built for regular fuel - 92-octane is perfectly adequate and saves money, cutting about 1 yuan per liter. The manual clearly states 92-octane unleaded as the recommended fuel. Some people claim 95-octane makes the car quieter, but that's mostly psychological; there's virtually no difference in actual power or fuel consumption. I tried 95-octane on highways and felt no noticeable acceleration improvement, just faster wallet depletion. I recommend choosing reputable gas stations to avoid engine damage from substandard fuel, and don't forget regular air filter checks during maintenance.
