[Lee]

Driving 160 kilometers at a steady speed of 120 km/h without sudden acceleration or braking requires approximately 15 liters of 92 gasoline. If the price of 92 gasoline is 6.14 yuan per liter, the cost would be around 100 yuan. Differences between 92 and 95 gasoline: 1. Composition: 92 gasoline consists of 92% isooctane and 8% n-heptane, while 95 gasoline consists of 95% isooctane and 5% n-heptane. The main difference lies in the purity of isooctane—the higher the purity, the stronger the gasoline's anti-knock performance, and consequently, the higher the price. 2. Stability: 95 gasoline has excellent stability. The octane rating of 92 gasoline is 92%, and that of 95 gasoline is 95%. The two types of gasoline should not be mixed, as doing so can harm the engine and significantly impact its lifespan. 3. Applicable models: When choosing between 92 and 95 gasoline, please refer to your car's user manual. Generally, cars priced around 100,000 yuan are sufficient with 92 gasoline, while cars priced around 300,000 yuan require 95 gasoline to meet the engine's demands.
