Is 95 gasoline more fuel-efficient than 92?
1 Answers
The difference between 95 and 92 gasoline lies in the better anti-knock performance of 95 gasoline, while fuel efficiency has little to do with the gasoline grade. Here are some relevant introductions about gasoline: 1. China's gasoline grade specifications are stipulated by the standard of gasoline products. Currently, there are three gasoline grades in use in China. 2. Gasoline grades are classified according to the octane number of gasoline. For example, 98 gasoline refers to gasoline fuel with anti-knock performance equivalent to 98% isooctane and 2% n-heptane. 3. The higher the gasoline grade, the better the anti-knock performance of the gasoline. 4. When adding gasoline, different grades of gasoline should be selected according to the engine compression ratio. The user manual of each car will indicate the gasoline grade used for the model. Using low-grade gasoline in a high-compression engine will lead to incomplete combustion of gasoline, resulting in a decrease in output power.
