What is 92 gasoline?

92 gasoline refers to fuel with an octane rating of 92 and a heptane content of 8, which is suitable for mid-range vehicles (those with relatively low compression ratios). On December 18, 2013, the General Administration of Quality Supervision, Inspection and Quarantine of China and the Standardization Administration of China jointly issued the fifth-stage national standard for automotive gasoline—"Automotive Gasoline" (GB17930—2013, replacing GB17930—2011). The difference between 92 gasoline and 95 gasoline: First, it can be clearly stated that there is no difference in fuel quality between 92 gasoline and 95 gasoline. 92 gasoline consists of 92% isooctane and 8% heptane, while 95 gasoline consists of 95% isooctane and 5% heptane. The reason 95 gasoline is slightly more expensive is due to its higher proportion of isooctane. Isooctane also has another function—anti-knock performance, meaning the higher the proportion of isooctane, the better the anti-knock performance. Every engine undergoes a comprehensive evaluation before leaving the factory, and based on the engine's performance and other data characteristics, anti-knock requirements are specified, which determines the appropriate gasoline grade to use.
I've been driving for over a decade, and 92-octane gasoline is our common standard fuel with an octane rating of 92, meaning it has good anti-knock properties that prevent engine knocking—that crackling noise. My regular family car has always used 92-octane, which is cost-effective and suitable for most people. A little extra knowledge: if the car has a high-compression engine, like some sports models, manufacturers recommend using 95-octane gasoline; otherwise, it might damage the engine. But for ordinary cars, 92 is sufficient and can even save some fuel costs. When choosing gasoline, I always refer to the owner's manual to avoid using the wrong type. By the way, the octane ratings differ by country—for example, 92 in the U.S. is roughly equivalent to 87, but in China, it's very common.
When I was helping out at the auto repair shop, car owners often asked what 92 gasoline is. It refers to gasoline with an octane rating of 92, which has strong anti-knock properties to prevent engine knocking issues. Most vehicles like SUVs and sedans can use 92 gasoline. Using a lower octane rating than recommended may cause knocking and damage the pistons. It's advisable to check the car manual for the recommended octane rating and avoid blindly opting for higher grades. To add: 92 gasoline offers good cost-performance and is suitable for city driving. However, for older engines or those with high compression ratios, switching to 95 might be better. In short, don't overlook this detail in daily maintenance.
I just learned to drive, and 92 octane is the regular gasoline we use, with an octane rating of 92 and good anti-knock properties. Every time I go to the gas station, I choose 92 octane—it's reasonably priced and suitable for my small car. Don't overthink the octane number; most car models are compatible with it, and the manual will also state the recommendation. If you accidentally choose the wrong one once, it's no big deal—just stick to it consistently in the long run. Simply put, don't worry about it damaging the engine.
