What is the difference between 92, 95, and 98 gasoline?
1 Answers
92-octane gasoline is more suitable for ordinary cars with relatively low technical content, 95-octane gasoline is more suitable for the vast majority of cars, and 98-octane gasoline is more suitable for high-end luxury cars and high-performance sports cars. The anti-knock performance of 98-octane gasoline is undoubtedly the best among these three types of gasoline, and it also has the highest production standards. More details are as follows: 1. The grade of gasoline is labeled based on the octane number, which does not indicate purity but rather the anti-knock property of gasoline. The higher the octane number, the better the anti-knock performance. The choice of gasoline for a car depends on the compression ratio of the cylinder—the higher the compression ratio, the higher the octane number required. 2. According to industry experts, the upgrade in the quality of National V gasoline comes with adjustments in the octane ratings. The octane rating represents the performance of the fuel—the higher the rating, the higher the octane number, which provides better power performance and lower fuel consumption for the car. 3. However, as the quality of the fuel is upgraded, the sulfur content is significantly reduced. While reducing sulfur content, some octane value is consumed, leading to a slight decrease in the octane rating. Consequently, slightly more fuel is needed to produce the same kinetic energy.
