Is There 97 Octane Gasoline?
3 Answers
There is 97 octane gasoline. Below is an introduction to 97 octane gasoline: 1. Introduction: 97 octane gasoline consists of 97% isooctane and 3% n-heptane. Engines with high compression ratios should use high-octane gasoline. If a high-compression engine uses low-octane gasoline, it may cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving performance. 2. Difference Between 93 Octane and 97 Octane Gasoline: The main difference between 93 octane and 97 octane gasoline lies in their anti-knock properties, which are determined by the octane rating. A higher octane rating indicates better anti-knock performance, but it does not mean the gasoline is cleaner. Using higher-octane gasoline does not make it more environmentally friendly. 3. Environmental Impact: In the current domestic gasoline blending process, an additive called methyl tert-butyl ether (MTBE) is commonly used to increase the octane rating of the fuel. However, MTBE can cause groundwater pollution. The aromatic hydrocarbons, olefins, and sulfur present in gasoline, when not fully burned, can produce PM2.5. These chemical substances, emitted through exhaust gases, can combine with the oxygen molecules from MTBE, leading to secondary production of even more PM2.5.
97 octane gasoline certainly exists. It is a high-octane fuel where the octane rating indicates anti-knock performance, which is particularly important for certain high-performance engines. I frequently see it available at gas stations, such as those operated by Sinopec or PetroChina. Using 97 octane gasoline can make the engine run more smoothly and reduce noise, especially suitable for high-compression ratio vehicles like sports cars or turbocharged models. However, it's slightly more expensive than regular gasoline, so the choice depends on your vehicle type and budget. If the owner's manual recommends higher-grade fuel, I would suggest using 97 octane as it can extend engine lifespan - just pay attention when refueling.
I've refueled with 97-octane gasoline multiple times during my drives, and it's absolutely true. I remember once during a long-distance trip, I filled up with 97-octane at a highway service area, and it felt like the engine got a boost of energy—more powerful and smoother acceleration. Nowadays, it's quite easy to find 97-octane at regular gas stations in cities, especially around major metropolitan areas. The higher octane rating of 97-octane fuel ensures cleaner combustion, which helps reduce carbon buildup inside the engine. Although it's a bit more expensive, it's worth the occasional fill-up for the sake of your car's maintenance. Don't worry about not finding it—gas station signs usually display it clearly.
