What is the difference between 93, 95, and 98 gasoline?
2 Answers
98 gasoline is different from 95 and 93 gasoline in the following ways: 1. Different quality levels: 98 gasoline has a higher octane value; 95 and 93 gasoline have lower octane values. Gasoline with a higher octane value has better anti-knock performance, and the engine runs more smoothly. 2. Different fuel consumption: 98 gasoline has lower fuel consumption; 95 and 93 gasoline have higher fuel consumption. The higher the gasoline grade, which means the higher the octane value, the less likely it is to cause knocking, and the better the engine's anti-knock performance during combustion. Additional information: Car 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 low cost without causing engine knocking.
The main difference between 93, 95, and 98 octane gasoline lies in their anti-knock performance. Anti-knock performance refers to the ability of gasoline to burn stably in the engine cylinders. The higher the number, the higher the octane rating, meaning 98 octane has better anti-knock properties than 93 octane. For most family cars, 93 or 95 octane is sufficient and fully meets the needs of standard engines—there's no need to pursue higher octane ratings. However, turbocharged or high-performance engines may require higher octane gasoline like 95 or 98. As for pricing, the higher the octane rating, the more expensive it is, with 98 octane typically costing a few cents more per liter than 93 octane. Personally, I've been using 95 octane for my daily driver, and it runs smoothly. Ultimately, it's most cost-effective to follow the manufacturer's manual recommendations—don't be fooled into spending extra on unnecessary premium fuel.
