What to Do If 98 Octane Gasoline Is Not Available on the Highway?

[StCharlie]

If 98 octane gasoline is not available on the highway, try to add as little gasoline as possible, which will not affect driving. Once the gas station has 98 octane gasoline, fill up the tank to dilute the lower-octane gasoline. Below is relevant information about 98 octane gasoline: 1. 98 Octane Gasoline: 98 octane gasoline refers to gasoline whose octane rating is equivalent to a mixture of 98% isooctane and 2% n-heptane. Engines with high compression ratios should use high-octane gasoline. Using low-octane gasoline in high-compression engines may cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Compared to other gasoline grades, 98 octane gasoline has stronger anti-knock properties and higher combustion value, providing more powerful performance. 2. Advantages of 98 Octane Gasoline: Compared to other gasoline grades, the advantages of 98 octane gasoline are mainly reflected in 'two highs and two lows': higher anti-knock properties and power performance, and lower harmful substances in gasoline and tailpipe pollution. Using higher-grade gasoline allows for greater engine power and smaller displacement, improving both performance and fuel economy.
