Will using 95-octane gasoline damage the Wuling Hongguang?

Generally speaking, it won't have much impact on the vehicle, but it's still recommended to use the fuel grade specified by the manufacturer. Here's relevant information: 1. Since gasoline is a mixture, the octane ratings we commonly encounter refer to different anti-knock indices (i.e., octane numbers). Strictly speaking, 92-octane and 95-octane gasoline shouldn't be mixed, though their chemical compositions and other aspects are relatively similar, with strong anti-knock properties. 2. Vehicle manufacturers clearly specify fuel requirements before leaving the factory. The appropriate gasoline grade depends on the engine's compression ratio. If a vehicle requiring high-octane fuel accidentally uses lower-octane fuel, the engine may experience knocking, reduced power, increased water temperature, and abnormal phenomena like metallic knocking sounds during operation.
As a seasoned driver of the Wuling Hongguang, I've driven this car for many years. Using 95-octane gasoline won't immediately damage the car, but it's not recommended either. The Wuling Hongguang's engine has a low compression ratio, and the manufacturer recommends 92-octane gasoline because it's designed to match lower-octane fuel. While 95-octane gasoline has higher octane and better anti-knock properties, it may not burn completely in a low-compression engine, leading to increased carbon deposits, higher fuel consumption, and, over time, reduced power and engine lifespan. I've seen a friend's car feel sluggish after switching to 95-octane, wasting money without any benefits. The key is to stick with 92-octane gasoline—it saves money and protects the car. If you accidentally fill up with 95-octane once, just use up the tank and switch back to 92. Remember, don't unnecessarily upgrade fuel during maintenance; it brings potential risks. Using the manufacturer's recommendation is the safest choice.
I'm an auto mechanic and have worked with many Wuling Hongguang models. Using 95-octane gasoline won't cause major harm to the engine, but since the engine's compression ratio isn't high, higher-octane fuel can lead to incomplete combustion. If the gasoline doesn't burn completely, carbon deposits may form in the cylinders or on the fuel injectors. Over time, this can result in reduced power output, fluctuating fuel consumption, and even engine warning lights. The Wuling Hongguang is designed for 92-octane gasoline, which provides sufficient anti-knock performance; switching to 95-octane is unnecessary, wasting money and adding maintenance burdens. I recommend checking the manual and sticking with 92-octane. If you accidentally fill up with 95-octane, don't panic—just use it up and switch back during normal maintenance to avoid frequent changes that could damage the fuel system. Matching the right fuel grade is key; unnecessary upgrades can create more problems.
