What is the difference between 95 and 92 gasoline for cars?
2 Answers
The differences between 95 and 92 gasoline are as follows: 1. Composition: The difference lies in the purity of isooctane. The higher the purity of isooctane, the stronger the anti-knock property of the gasoline, and accordingly, the higher the price. 2. Stability: 95 gasoline has particularly good stability, and it is more flammable. The octane value of 92 gasoline is 92%, while that of 95 gasoline is 95%. 95 gasoline is particularly flammable, so it is less resistant to burning. The two types of gasoline cannot be mixed, as mixing gasoline can cause engine problems. 3. Applicable models: Generally, cars priced around 100,000 yuan can use 92 gasoline, while cars priced around 300,000 yuan require 95 gasoline to meet the engine's needs.
As a seasoned driver who frequently uses a family car, I believe the main difference between 92 and 95 lies in the octane rating. 95 has a higher octane value and better anti-knock performance, making it suitable for high-compression engines like turbocharged models or sports cars. However, my car is a regular coupe with an engine designed to be compatible with 92, so I always use it to save money—the difference can be tens of yuan per tank. If the octane rating is low, occasionally using 95 won’t cause issues, but if the engine requires 95 and you consistently use 92, it may lead to knocking, increased fuel consumption, and engine damage. I recommend checking the owner’s manual instead of blindly opting for premium fuel. Additionally, with fluctuating fuel prices, it’s more practical to choose the right time or take advantage of discounts when refueling rather than chasing high-grade fuel.
