How to switch from 95 to 92 gasoline?
2 Answers
Different grades of gasoline do not react with each other, and occasional mixing has little impact on the vehicle. Therefore, you can directly add 92 gasoline to the fuel tank. Below are the differences between 92 and 95 gasoline: 1. Heptane content: 95 gasoline contains 5% heptane; 92 gasoline contains 8% heptane. 2. Isooctane content: 95 gasoline contains 95% isooctane; 92 gasoline contains 92% isooctane. 3. Anti-knock performance: Different gasoline grades represent different anti-knock properties. The higher the gasoline grade, the better the anti-knock performance. 95 gasoline has better anti-knock performance than 92 gasoline.
Switching to 92-octane gasoline is very simple. Just go to the gas station and fill up with 92-octane when the tank is almost empty. No special preparation is needed. I've been driving for over ten years and used to use 95-octane, thinking it was more premium. Later, a friend suggested switching to 92-octane, so I did. There's no noticeable difference in how the car drives. The engine adjusts the ignition timing automatically, so there's no need to worry about issues. 92-octane is much cheaper—filling up a tank saves dozens of yuan, and over time, it adds up to significant savings. For city driving, 92-octane is more than enough, as engines are designed to be compatible with various fuel grades. After switching, just avoid stomping too hard on the accelerator and maintain normal driving habits. 92-octane gasoline is also more widely available, making it convenient to find anywhere.
