What is the difference between 98-octane and 95-octane gasoline?
2 Answers
The differences between 98-octane and 95-octane gasoline: 1. Different quality levels: 98-octane gasoline has a higher octane rating, while 95-octane gasoline has a lower octane rating. Fuel with a higher octane rating has better anti-knock performance, resulting in smoother engine operation and reduced wear. 2. Different fuel consumption: 98-octane gasoline has lower fuel consumption, while 95-octane gasoline has higher fuel consumption. The higher the gasoline grade (i.e., the higher the octane content), the less likely it is to cause knocking, and the better the engine's anti-knock performance during combustion. Vehicle owners should choose gasoline based on the engine's compression ratio. Vehicles with higher compression ratios should use higher-grade gasoline to ensure strong power output and lower costs without causing engine knocking.
As a car enthusiast, I'm often asked about the difference between 98 and 95 octane gasoline. The key lies in the octane rating - 98 has a higher octane value, meaning it has better anti-knock performance under high engine temperature and pressure, making it suitable for high-compression engines like sports cars or turbocharged vehicles, providing smoother power output and protecting the engine from damage. 95 octane has a slightly lower rating and is more suitable for regular family cars since their engine designs are less sensitive to knocking. In actual tests, using 98 octane gasoline in city driving delivers noticeably smoother acceleration, though it's slightly more expensive, costing a few cents more per liter on average. All factors considered, you should choose fuel according to your vehicle's manual rather than following trends blindly. Using low-octane fuel in the wrong car may cause engine knocking or premature wear, increasing maintenance costs.
