What is the current equivalent of the previous 93-octane gasoline?
3 Answers
The previous 93-octane gasoline is now equivalent to 92-octane gasoline. Here is the relevant information: 1. Fuel grade: Automobile fuel grades were introduced after the National V standard, with 92-octane gasoline replacing 93-octane gasoline and 95-octane gasoline replacing 97-octane gasoline. 2. Regulation: Vehicles must use the specified fuel grade; otherwise, engine problems may occur. Below is additional information on the differences between 95# and 92# gasoline: 1. Composition ratio: 95-octane gasoline contains 95% isooctane and 5% n-heptane, while 92-octane gasoline contains 92% isooctane and 8% n-heptane. 2. Anti-knock performance: 95-octane gasoline has higher anti-knock performance, whereas 92-octane gasoline has lower anti-knock performance.
The previous 93-octane gasoline is now equivalent to the current 92-octane standard. I experienced this myself—back in 2017 when China upgraded to the National V fuel standard, 93-octane was replaced by 92-octane. At the time, I had just bought a new car and noticed the change in octane rating at the pump. After asking a gas station attendant, I learned that I could simply switch to 92-octane, and the car would run just as smoothly with no noticeable difference in fuel consumption. I even looked it up—the upgrade was for environmental reasons, reducing impurities in the fuel and lowering emissions. While I do feel a bit nostalgic for the old octane rating, it’s definitely progress overall. My advice to fellow drivers with older cars: don’t overthink it—just keep fueling up as usual, and focus on regular maintenance.
The old 93-octane gasoline is equivalent to the current 92-octane. As a young person with a used car, the manual recommends 93-octane, but I directly use 92-octane without any issues, and the power and noise feel the same. Friends say this is due to the standard upgrade, which helps prevent engine knocking or carbon buildup. I suggest checking the label on the fuel tank cap when refueling and avoiding other grades to save money at the expense of the car. The change is aimed at reducing pollution, which I fully support since cleaner air benefits everyone.
