Does filling 95 gasoline with 92 have any impact on the car?

Filling 95 gasoline with 92 by mistake occasionally has little impact on the car, as long as it does not happen frequently. The difference between 95 and 92 gasoline: The biggest difference between 92 and 95 gasoline is the isooctane content. 92 gasoline contains 92% isooctane, while 95 gasoline contains 95%. The octane number of 95 gasoline is higher than that of 92 gasoline, and this octane number can improve the stability of the gasoline. Precautions for refueling: Do not overfill the tank. If the tank is overfilled, gasoline may overflow through the vent hole, which can lead to spontaneous combustion if exposed to an open flame, with unimaginable consequences; Try to avoid refueling only when the fuel light comes on. If you frequently wait until the fuel light comes on to refuel, the fuel pump will not receive proper lubrication and cooling, ultimately leading to a reduced lifespan of the fuel pump.
I've always been concerned about car performance, and switching from 95-octane to 92-octane fuel can indeed have an impact. The lower the octane number, the weaker the anti-knock capability. If your car's engine has a high compression ratio, such as turbocharged or sports models, using 92-octane fuel can easily cause knocking. It sounds like engine knocking, which can damage pistons and valves, leading to reduced power and increased fuel consumption over time. However, occasionally using the wrong fuel once isn't a big issue; just burn it off as soon as possible and switch back to 95-octane. The key is to follow the user manual's recommendations—don't risk it to save a little money. Regular engine checks are essential to ensure safe and comfortable driving.
I usually drive a city commuter car, and when using 92-octane fuel, the car responds noticeably slower with increased noise and engine vibration. Once, I accidentally filled up with 92-octane and felt a lack of power when going uphill. A friend warned me that lower-octane fuel increases the risk of engine knocking. While short-term use may not cause major issues, frequently switching fuel grades can accelerate wear and even shorten engine life. Solutions include using high-quality fuel additives or burning through the current tank quickly before switching back to the recommended octane. Fuel consumption may slightly increase, making it less cost-effective in the long run. For daily refueling, it's best to consistently use the appropriate octane rating to ensure peace of mind and protect your vehicle.
