What is the current equivalent of 93-octane gasoline?

Vehicles that originally used 93-octane gasoline now correspond to 92-octane gasoline after the fuel reform. 92-octane gasoline is the replacement for 93-octane gasoline under the National V standard, while the former 97-octane gasoline is now 95-octane. More relevant information is as follows: 1. Composition: Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, with its octane number set at 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane number set at 0. 2. Gasoline grade: If the gasoline is labeled as 92, it means that this grade of gasoline has the same anti-knock properties as standard gasoline containing 92% isooctane and 8% n-heptane. The so-called gasoline grade is actually the numerical value of the octane rating.
I've been driving for many years and remember when 93-octane gasoline was very common, especially in older car models. Nowadays, gas stations have switched to new grades like 92, 95, and 98. In fact, 93-octane is equivalent to the current 92-octane, which is due to the country's upgraded gasoline standards, such as the China VI emission regulations, making gasoline cleaner and the octane rating calculation more precise. I was a bit worried when I switched, but after trying 92-octane, my car ran normally with no loss in power, and I even saved a bit on fuel costs. It's also better for the environment, reducing harmful emissions. If you're an owner of an older car, I recommend simply switching to 92-octane and avoiding unnecessary additives. However, newer cars might require 95-octane or higher to match their engines, so it's safest to follow the manual. Overall, these changes are for everyone's health and cleaner air.
From a technical perspective, gasoline grades represent octane ratings. In the past, 93-octane was short for Research Octane Number (RON) 93. With the recent standard adjustment, new measurement methods were adopted, and 93-octane has been reclassified into the 92-octane range, aiming to improve fuel efficiency and reduce pollution. I've analyzed the data—this upgrade makes octane calculations better suited for modern engines, reducing the risk of knocking. Regular car owners can directly switch to 92-octane fuel without worrying about damaging their vehicles. An added benefit is the optimized gasoline additives, which protect internal engine components. Remember to check oil pressure regularly, and if the car has a special design, consider upgrading to 95-octane for better performance. Internationally, standards vary—Europe and the U.S. have different norms, but the core principles remain the same.
As a daily driver, I used to use 93-octane gasoline, but recently I've noticed it's become rare at gas stations, with 92 and 95 octane now being the mainstream. 93-octane is essentially equivalent to 92-octane due to the upgrade to more environmentally friendly standards. When switching, be careful not to mix old and new fuel—just fill up with 92-octane. I've personally tested it, and there's no change in performance, with fuel consumption remaining stable. I recommend checking the recommended octane rating on your fuel tank cap to avoid any surprises. The background to this change is the China VI policy, which has driven this reform to help reduce air pollution. Simply put, for car owners, 92-octane is a safe choice—cost-effective and efficient.
