Can a car that uses 92 octane gasoline also use 95 octane gasoline?
1 Answers
A car that uses 92 octane gasoline can also use 95 octane gasoline, but it is not recommended for long-term use. Engines with a compression ratio between 8.5 and 9.5 typically use 92 octane gasoline, while engines with a compression ratio greater than 9.5 usually use 95 octane gasoline. Occasional use once or twice will not have a significant impact. Differences between 92 and 95 octane gasoline: Compression ratio differences: Generally, cars with a compression ratio between 8.5 and 9.5 should use 92 octane gasoline, while cars with a compression ratio greater than 9.5 should use 95 octane gasoline. Octane rating differences: 92 octane gasoline has a lower octane rating than 95 octane gasoline. Specifically, 92 octane gasoline contains 92% isooctane, while 95 octane gasoline has an octane rating of 95%. Price differences: 92 octane gasoline is cheaper per unit than 95 octane gasoline. Gasoline grade selection: Common gasoline grades in China mainly include 92 octane and 95 octane. The gasoline grade indicates the octane rating of the gasoline, with higher octane ratings providing better anti-knock performance. Diesel grades are different from gasoline, as diesel grades represent the freezing point. Refueling precautions: Try not to wait until the fuel warning light comes on before refueling. The fuel pump is located inside the fuel tank and operates at a high temperature when continuously working. Being immersed in fuel helps to effectively cool it down. When the fuel warning light comes on, it means the fuel level is below the fuel pump. If you always wait for the light to come on before refueling, it will shorten the lifespan of the fuel pump. Additionally, having too little fuel or running out of fuel can potentially burn out the fuel pump. If the car has been driven over 30,000 kilometers, extra caution is needed. When the fuel level is too low, the fuel pump may draw in sediment from the bottom of the tank, which can block the fuel pump or obstruct the fuel line.
