Is 93 gasoline the current 92 gasoline?
1 Answers
92 gasoline is the previous 93 gasoline, they are the same type of gasoline. 92 is the National V standard, equivalent to the original 93 National IV standard. Currently in China's market, gasoline comes in grades such as 90, 93, 95, and 97. These numbers actually represent the octane rating of the gasoline, indicating its anti-knock performance, and are unrelated to the cleanliness of the gasoline. Since the nationwide unified supply of National V standard was implemented, 93 gasoline corresponds to 92, and 97 corresponds to 95, rather than the current 98. The higher the octane number, the better the anti-knock performance. Because emission standards have become more stringent, in the long run, the upgraded octane numbers can not only reduce pollutant emissions but also extend the vehicle's service life and reduce maintenance costs. Furthermore, it decreases corrosion to the car engine and deposits in the intake system, protecting the engine and emission system, providing better protection for the vehicle. The recommended gasoline grade for a car can be found on the fuel tank cap. When using the vehicle, it is essential to strictly adhere to the specified gasoline grade. Otherwise, it may affect engine performance, leading to insufficient power, increased noise, and heightened vibrations, which in turn can increase fuel consumption. Therefore, it is crucial to use the specified gasoline grade when refueling.
