Does 93 gasoline correspond to 92 or 95?

[McPenelope]

93 gasoline corresponds to 92. Here is the relevant introduction: 1. Fuel grade: The automobile fuel grade was introduced after the China V standard, in which 92 gasoline replaces 93 gasoline, and 95 gasoline replaces 97 gasoline. 2. Regulation: Motor vehicles must use the specified fuel grade, otherwise engine problems will occur. The following is extended information on the differences between 95# and 92# gasoline: 1. Composition ratio: 95 gasoline contains 95% isooctane and 5% n-heptane; 92 gasoline contains 92% isooctane and 8% n-heptane. 2. Anti-knock performance: 95 gasoline has high anti-knock performance; 92 gasoline has low anti-knock performance.

I've driven quite a few imported cars and encountered 93-octane gasoline overseas. This stuff is considered premium fuel in the US, equivalent to the Premium grade. In terms of octane rating, 93 AKI standard is approximately 98-99 RON, similar to China's 98-octane. Using the wrong fuel can damage the engine—for example, using 92-octane may cause knocking and cylinder wear. I recommend checking your vehicle's manual. If it requires 93-octane, opt for China's 98-octane for safety, though 95-octane will work in a pinch—don't skimp and risk damaging your car. When refueling, I always match the fuel grade to ensure smooth performance and extend engine life. Since 93-octane isn't commonly available at Chinese gas stations, just follow the recommended octane rating.

When I first bought a car, I was completely confused about gasoline grades. The 93 octane rating usually isn't a Chinese specification—it belongs to the high-octane category in international standards. After researching, I learned that 93 corresponds to the AKI system, with an octane rating of approximately 98 RON, making it closer to China's 98 octane. Using 92 octane might cause engine knocking and reduced power, which I experienced firsthand. Now, I mainly use 95 octane—it's both economical and protects the vehicle. Remember, always check with the dealership or the manual to avoid unnecessary repair costs.

The gasoline octane rating indicates its anti-knock capability. In the US, 93 octane is considered premium fuel. Simply put, 93 AKI (Anti-Knock Index) in the US is equivalent to 98 RON (Research Octane Number) in China, so 98 octane is the most suitable choice. Avoid using 92 octane randomly as it may damage the engine.
