Is 93 gasoline the same as the current 92 gasoline?

[RuthDella]

92 gasoline is the same as the previous 93 gasoline; they are the same type of fuel. Gasoline classification: Currently, in the domestic market, gasoline is labeled with numbers such as 90, 93, 95, and 97. These numbers represent the octane rating of the gasoline, which indicates its anti-knock performance and has nothing to do with the cleanliness of the fuel. How to choose gasoline: It is more scientific and economical to refuel according to the engine's compression ratio or the requirements specified in the car's manual, as this maximizes the engine's efficiency. The main basis for selecting the gasoline grade is the engine's compression ratio. Blindly using higher-grade gasoline not only results in sluggish acceleration but also fails to utilize its high anti-knock performance advantage, leading to unnecessary financial waste.

I remember that 93-octane gasoline was commonly seen at gas stations before. It was the old national standard type with slightly higher octane rating and anti-knock performance. Now with the upgrade to the National V standard, 92-octane gasoline has become widespread. Its octane rating is around 92, slightly lower than 93, but it's more environmentally friendly with cleaner emissions. My Volkswagen has been running for ten years, and the manual requires 93 or above 90 octane. Using 92-octane is fine, the power remains stable, and it saves some fuel costs. Don’t worry about the car not adapting well—modern engine technology is strong and highly adaptable. However, high-end cars might require 95-octane, so it’s safest to check the fuel cap label or the manual. When refueling, always ask the attendant to confirm the local grade to avoid using the wrong one and affecting performance. Overall, 93 and 92 are not the same, but 92 can be used as a cost-effective alternative.

When I first bought a car, I also confused 93 and 92. In reality, different standards represent different octane ratings. 92 has replaced 93 as the new national standard, with a slightly lower octane value but optimized combustion efficiency, and it's still anti-knock for most vehicles. For example, my Honda's manual specifies starting with 92, and cars that previously used 93 are compatible with 92. Always check your vehicle's label before refueling instead of guessing from memory, as engine designs vary and may not be suitable. Price-wise, 92 is sometimes a few cents cheaper, and after filling up a few times, I noticed no issues with power remaining strong. It's advisable to understand the environmental changes driving the updates in fuel grades and not worry about compatibility.

Gasoline octane rating is a numerical unit measuring anti-knock capability. The 93 octane indicates 93% octane value, now rarely seen; 92 octane replaces it with approximately 92% octane value and wider applicability. Under China V standards, 92 octane is predominant for lower emissions and higher efficiency. Many economy cars perform well on 92 octane—avoid mixing fuels and always check the manual to confirm engine requirements.

Fueling habits have changed quite a bit. Years ago, 93 octane was popular with its slightly higher octane rating and better anti-knock performance. Now 92 octane has become mainstream with its 92 octane rating, better environmental protection, and lower emissions. My old car's manual specifies 93, but using 92 hasn't caused major issues, just occasional slight power reduction. It's recommended to choose based on the vehicle's year—don't insist on older grades. The purpose of upgrading standards is to reduce pollution. Check the fuel cap or manual to ensure safety and avoid engine damage.
