Is 98 More Durable Than 95?

[DelLondon]

98-octane gasoline is not necessarily more durable than 95-octane. A higher octane rating does not mean better gasoline quality, as there is no direct correlation between gasoline octane ratings and fuel quality. Below are the relevant details: 1. The octane rating of gasoline only represents its octane value. Both 95-octane and 98-octane gasoline are high-octane fuels. Compared to 95-octane, 98-octane gasoline has an octane value that is 3 units higher. Increasing the octane value of unleaded gasoline by even one unit requires greater technical difficulty and higher processing costs. Therefore, high-octane gasoline is priced higher than low-octane gasoline. 2. Different engines use gasoline with different octane ratings, primarily determined by the engine's compression ratio. Generally, engines with a compression ratio above 8.0 should use 92-octane gasoline; those above 9.0 should use 95-octane gasoline, and engines with a compression ratio above 10.0 should use 98-octane gasoline.
