Is There a Big Difference Between 95 and 92 Gasoline?

[McKarter]

The differences between 95 and 92 gasoline are as follows: 1. The anti-knock properties of 95 and 92 gasoline are different, which means their iso-octane values differ. 92 gasoline has an octane rating of 92, meaning it has the same anti-knock properties as a standard gasoline containing 92% iso-octane and 8% n-heptane. Similarly, 95 gasoline has the same anti-knock properties as a standard gasoline containing 95% iso-octane and 5% n-heptane. The higher the octane rating, the more iso-octane the gasoline contains, and the stronger its anti-knock ability. Generally, you just need to use the gasoline recommended by the manufacturer and don't necessarily need to pursue higher-octane gasoline. 2. 92 gasoline is more prone to knocking. To avoid knocking, the ignition timing of the spark plug must be delayed. The result of delayed ignition timing is relatively weaker power. In comparison, 95 gasoline is less prone to knocking, and the computer can control a relatively earlier ignition timing, so the power performance is relatively stronger. Simply put, it's like a sprint race—the speed of the start can affect the final result.
