Is Ethanol Gasoline 92 or 95?

In fact, 92, 95, and 98 are all ethanol gasoline. The different gasoline grades are due to different additives, and ethanol is added later in proportion. When you go to the gas station to refuel, if there is the letter 'e' before the gasoline grade, it means it is ethanol gasoline. Here is more information about ethanol gasoline: 1. Ethanol gasoline is an alternative energy source formed by blending fuel ethanol processed from grains and various plant fibers with regular gasoline in a certain ratio. According to China's national standard, ethanol gasoline is blended with 90% regular gasoline and 10% fuel ethanol, making it a mixture. Adding an appropriate amount of ethanol to gasoline as a vehicle fuel can save petroleum resources, reduce air pollution from vehicle emissions, and also promote agricultural production. 2. The main disadvantages of ethanol gasoline are that users feel it has reduced power compared to regular gasoline, increased fuel consumption, and it is prone to vapor lock and stalling in hot weather. Additionally, since ethanol gasoline separates once it comes into contact with water, it cannot be transported via low-cost pipelines. The storage and transportation cycle of ethanol gasoline is only 4-5 days, which affects the convenience of using ethanol gasoline.

Recently, I've been driving an economy car and frequently using ethanol-blended gasoline. Ethanol gasoline comes in different grades, such as 92 and 95, which depend on the base octane rating and ethanol content. In China, ethanol gasoline is typically E10 type, containing about 10% ethanol. The 92-grade ethanol gasoline has a lower octane rating, making it suitable for regular household cars—small-displacement engines can save some money with it, though fuel consumption might be slightly higher due to ethanol's lower energy density compared to pure gasoline. The 95-grade ethanol gasoline has a higher octane rating, making it more suitable for performance-oriented or larger-displacement vehicles. I recommend car owners check their vehicle manuals to choose the appropriate grade and avoid switching blindly to prevent engine issues like acceleration knocking or carbon buildup. Ethanol gasoline is environmentally friendly, reducing tailpipe emissions, but long-term use may corrode fuel lines, so mixing fuels or regular inspections are advisable.

As an environmentally conscious individual, I believe ethanol-blended gasoline is an excellent choice for promoting green mobility. It comes in two grades: 92 and 95. The 92-octane ethanol gasoline has a lower octane rating, making it suitable for mid-to-low-end vehicles, while the 95-octane variant is designed for premium models. The addition of ethanol significantly reduces carbon dioxide emissions, benefiting air quality. However, ethanol increases volatility, which may impact fuel efficiency – compared to pure 95-octane gasoline, 92-octane ethanol blend might consume about 5% more fuel. In practical use, I've found 92-octane ethanol gasoline more cost-effective for urban driving, while recommending 95-octane ethanol for long-distance trips to ensure stable performance. In conclusion, promoting ethanol-blended gasoline contributes to sustainable development, but vehicle compatibility must be considered.

I've worked in an auto repair shop and understand the basics of ethanol-blended gasoline. Both 92 and 95 octane grades have ethanol versions, with the numbers directly corresponding to the octane rating's anti-knock performance. For regular car engines with lower compression ratios, 92 ethanol is sufficient and less likely to cause knocking; high-performance vehicles should opt for 95 ethanol to protect the engine. Ethanol itself has a very high octane rating, which can enhance overall performance, but its lower heat value may lead to ignition delays or cold start difficulties. When using it, avoid mixing different fuel types and clean the fuel injectors regularly to prevent corrosion. Simply put, choose the appropriate octane grade based on your vehicle's requirements.
