Can a Car Using 92 Octane Gasoline Use 95 Octane?

[MacGia]

92 octane gasoline cars can use 95 octane gasoline. The differences between the two are as follows: 1. The main difference lies in the ratio of isooctane to n-heptane. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. Isooctane has better anti-knock properties, so 95 octane gasoline has better anti-knock performance than 92 octane gasoline and is less prone to knocking. 2. Cars using 92 octane gasoline, compared to those using 95 octane, need to reduce the compression ratio and match the corresponding ignition timing. The higher the engine compression ratio, the more fully the gasoline vaporizes, the higher the combustion efficiency, and the stronger the power. This is why cars using 95 octane gasoline have stronger power than those using 92 octane.
