Can You Add 95 After Adding 98?

[VincentFitz]

You can add 95 gasoline after adding 98 gasoline. Here is some relevant information about gasoline usage: 1. Reasons: Using lower-octane gasoline in a high-octane vehicle can severely affect the engine's normal operation, leading to knocking. In severe cases, it may reduce the engine's lifespan and increase maintenance costs. Conversely, using higher-octane gasoline in a low-octane vehicle can cause incomplete combustion, resulting in fuel wastage. Therefore, for vehicle safety, it is best to use them separately. 2. Special Cases: Gasoline is a mixture, and the octane rating we usually refer to indicates the gasoline's anti-knock index (i.e., octane number). Strictly speaking, 98-octane and 95-octane gasoline should not be mixed. However, since their chemical compositions and other aspects are relatively similar and both have strong anti-knock properties, mixing them generally does not cause significant issues. Nonetheless, to ensure vehicle safety, it is still best to use them separately.
