What Are the Types of Gasoline at Gas Stations?

Gasoline is categorized into leaded gasoline, unleaded gasoline, and another type called ethanol gasoline. Common gasoline grades include 89, 92, 95, and 98. The differences between these types of gasoline are as follows: 1. Different Octane Ratings: 89 gasoline contains 89% isooctane; 92 gasoline contains 92% isooctane; 95 gasoline contains 95% isooctane; and 98 gasoline contains 98% isooctane. 2. Different Anti-Knock Properties: The higher the gasoline grade, the higher the isooctane content, resulting in stronger anti-knock performance. 3. Different Applicable Compression Ratios: Different gasoline grades have varying compression ratio requirements. The higher the engine's compression ratio, the higher the required gasoline grade. Generally, engines with a compression ratio greater than 8.0 should use 92 gasoline; those with a compression ratio greater than 9.0 should use 95 gasoline; and engines with a compression ratio greater than 10.0 should use 98 gasoline. 4. Different Applicable Models: 92 gasoline is suitable for ordinary cars with low technical specifications, 95 gasoline is suitable for most cars, and 98 gasoline is suitable for luxury cars and sports cars.
When refueling, I often see different grades of gasoline, mainly three types: 87 octane regular gasoline, 89 octane mid-grade gasoline, and 91 octane or higher premium gasoline. The 87 octane is the cheapest and most commonly used, suitable for most family cars. For example, my old car uses it, saving money and being practical. The 89 octane is slightly better, suitable for some cars that require stronger power. The 91 octane is for sports cars or high-performance vehicles, with better anti-knock properties. Additionally, some gas stations offer E10 gasoline, which contains 10% ethanol, is more environmentally friendly but may increase fuel consumption. My experience is not to casually use higher octane gasoline, as it may waste money without much effect. Be sure to check your car’s manual to see what grade is recommended to avoid engine problems. Gasoline grades vary by region; for example, premium gasoline is more common in cities, while rural areas have fewer choices. When choosing gasoline, also pay attention to price fluctuations. After the recent rise in oil prices, I’ve been focusing more on cost-saving options.
I understand that gasoline is categorized into several basic types, including 87 Regular, 89 Mid-Grade, and 91 Premium. Higher octane numbers indicate better anti-knock performance, making 91 Premium more suitable for turbocharged vehicles. There are also blended fuels like E10, which contains 10% ethanol, helping to reduce emissions. I believe it's important to match the fuel type with the vehicle's design—regular gasoline is sufficient for most family cars, and blindly opting for higher grades is both costly and unnecessary. Price differences between grades can be significant, with premium gasoline being notably more expensive. I recommend checking your car's manual for the recommended fuel type before refueling to avoid engine damage. Expanding on this, environmentally friendly fuels like E85 are more popular abroad, but here, E10 is the main option. If your vehicle supports it, it's worth trying for the sake of environmental conservation.
When I first started driving, I was always confused about gasoline grades. Later, I learned there are basically three types: 87 regular gasoline is the most common and cheapest, 89 mid-grade gasoline is slightly better, and 91 premium gasoline is the most expensive but required for high-performance cars. I've also seen E10, which is ethanol-blended green gasoline. I usually just fill up with 87 to save money and hassle. Remember to use the grade your car requires, otherwise it might damage the engine.
I prioritize eco-friendly gasoline types. Common octane ratings at gas stations include 87, 89, and 91, but I pay special attention to E10 fuel, which contains 10% ethanol and has lower carbon emissions for greater sustainability. Although premium 91-octane gasoline offers better performance, its higher price makes E10 my regular choice as it reduces reliance on fossil fuels and is more environmentally friendly, despite slightly higher fuel consumption. It's crucial to confirm vehicle compatibility to avoid engine issues. Price comparisons show E10 is usually much cheaper than premium gasoline, striking a good balance between economy and environmental protection. Always check the manual's recommendations to prevent incorrect selection.
