How much 92 left can be added with 95?

[DeVincent]

Regardless of how much 92 gasoline is left, you can add 95 gasoline. Since 92 and 95 gasoline will not cause any chemical reaction, there is no need to worry about mixing them. If the car requires 92 gasoline, you can mix 92 and 95 gasoline. However, if the car requires 95 gasoline, it is not recommended to mix 92 and 95 gasoline, as it may easily cause knocking in the engine. Here are some related information: 1. Knocking is an abnormal combustion phenomenon in the engine, which can affect the engine's power output and fuel efficiency. 2. Knocking can affect the current engine's compression stroke. When the engine is in the compression stroke, the piston moves upward, compressing the combustible mixture. After compression, the temperature and pressure of the combustible mixture will rise. If the gasoline's stability is poor, the combustible mixture may ignite prematurely.
