Can I use 95 gasoline if 92 is not available?
1 Answers
It is acceptable to occasionally use 95 gasoline when 92 is unavailable, as gasoline is a mixture and the composition of different grades is quite similar. However, it is not recommended to use 95 gasoline for a long time. The octane number of 95 gasoline is higher than that of 92, which may cause engine damage in severe cases. The grade of gasoline is an indicator of anti-knock performance, which is basically unrelated to cleanliness, power, or combustion value. The higher the gasoline grade, the stronger its ability to resist engine knocking. The difference between 92 and 95 is that 95 is more resistant to knocking than 92. It is also advisable not to mix different grades of gasoline. Short-term mixing will not cause significant harm to the car, but the hazards of long-term mixing should not be ignored. Mixing different grades of gasoline for a long time will affect the service life of the car's ignition system, fuel injectors, and spark plugs, leading to an earlier need for major repairs. The differences between 92 and 95 gasoline are as follows: Different octane numbers: 92 gasoline: Contains 92% isooctane and 8% n-heptane. 95 gasoline: Contains 95% isooctane and 3% n-heptane. Different gasoline quality levels: The grade of gasoline represents its octane number. A higher grade indicates a higher octane number, which means better anti-knock performance. This results in smoother engine operation, reduced wear on the car, and better protection for the engine. Different octane numbers lead to different anti-knock performances. Gasoline is a mixture produced by adding a certain amount of anti-knock agents to the same base gasoline, resulting in gasoline with different anti-knock properties. Different gasoline components, such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components obtained from petroleum refining, are refined and blended with high-octane components, primarily used as fuel for automotive spark-ignition internal combustion engines. The chemical compositions of these two grades of gasoline are quite similar, but 95 gasoline has higher fuel efficiency and provides more power for the car. Generally, naturally aspirated cars use 92 gasoline, while turbocharged cars use 95 gasoline.
