Will mixing 95 and 92 gasoline affect the car?

[EleanorDella]

95 gasoline cannot be directly mixed with 92 gasoline, which will affect the car. The introduction of the two gasolines is as follows: 95 gasoline: It contains 95% isooctane and 5% n-heptane. High-octane gasoline should be used when the engine compression ratio is high. If low-octane gasoline is used with a high compression ratio, it will cause abnormal combustion, resulting in knocking, increased fuel consumption, and lack of power. Of course, high-compression engines can also use low-grade gasoline, but you should not blindly choose gasoline grade based on compression ratio. Instead, follow the manufacturer's requirements for refueling. 92 gasoline: 92 gasoline has an octane rating of 92 and contains 8% n-heptane, which is suitable for mid-range cars (with relatively low compression ratios).
