What is the current equivalent of 93-octane gasoline?
2 Answers
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.
