Can I use 92 octane gasoline if the car specifies 93 or above?
2 Answers
93 octane gasoline is now known as 92 octane gasoline, so using 92 octane is acceptable. 93 octane was the standard under China's National IV emission standards, while 92 octane is the new standard under National V. Whether the labeling will change in the future remains unknown. 92 octane gasoline has an octane rating of 92 and a heptane rating of 8, making it suitable for mid-range vehicles. Here is some additional information: Gasoline is a petrochemical product. Whether it's 93 octane or 97 octane, they are essentially the same hydrocarbons, with differences in certain components leading to varying knock points. Compatibility: These differing components are fully miscible with the base oil, and their physicochemical indicators are identical. When mixed, they still remain gasoline.
Having driven for over a decade, I deeply understand that fueling a car should never be taken lightly. The car manual specifies gasoline with an octane rating of 93 or higher. If you insist on using 92, there might not be immediate issues, but the engine will eventually develop problems. My car has a high-compression engine, and once, trying to save money, I used 92. During acceleration, the engine started knocking, sounding like a tractor. When the engine was opened up for repairs, it was full of carbon deposits, and even the connecting rods were deformed. Since then, I never take risks and always choose fuel with an octane rating of 93 or higher to protect the engine. Saving a little on fuel in the short term leads to double the repair costs in the long run—it's simply not worth it. Maintaining a car is like raising a child; neglecting the small things leads to big regrets when disaster strikes.
