How much 95 gasoline left can be switched to 92?

[AlexandraRose]

No matter how much 95 gasoline is left, you can add 92 gasoline as long as the car allows the use of 92 gasoline. 92 gasoline and 95 gasoline can be mixed. The following are the details about gasoline grades: 1. The meaning of gasoline grades: The gasoline grade represents the anti-knock performance of the fuel. The higher the grade, the better the anti-knock performance. It is worth mentioning that the gasoline grade has little to do with the quality of the gasoline itself. It does not mean that the higher the grade, the better the gasoline, or that the higher the grade, the less impurities or the purer the gasoline. 2. Choose according to the engine: The choice of which grade of gasoline should be based on the compression ratio of the engine, and do not blindly use high-grade fuel, because if the compression ratio is not enough, the advantage of high anti-knock performance cannot be brought into play, and it will also cause a waste of money. At the same time, choosing gasoline that does not match the compression ratio will cause the gasoline mixture to explode in advance when the engine piston is compressed, affecting the power of the car.
