What to do if 92 gasoline is added to a 95 tank?
2 Answers
If the car should use 95 gasoline but 92 gasoline is added, in principle, using a lower octane rating gasoline in small amounts will not cause major problems to the engine, but it may affect the car's performance. Precautions for adding gasoline: 1. When using gasoline, avoid mixing it with kerosene or diesel. Doing so will increase knocking, severely damage the engine's lubrication, and shorten the engine's lifespan. 2. Do not use gasoline that has been stored for a long time and has deteriorated, as using deteriorated gasoline can cause severe engine gumming and carbon deposits. 3. Avoid direct sunlight and regularly clean the fuel tank and gasoline filter.
I've been driving for many years and have encountered a few instances of misfueling. If your car requires 95-octane gasoline but you accidentally filled it with 92-octane, don't panic, but take immediate action. 95-octane has better anti-knock properties, while 92-octane is more prone to causing engine knocking, which manifests as engine shaking and increased noise. Prolonged use can damage the engine's lifespan. If you only added a small amount of 92-octane, immediately go to the gas station and top up with 95-octane to dilute it. If you filled the tank completely with 92-octane, avoid high-speed driving or sudden acceleration; instead, drive slowly to consume the tank, and consider adding an anti-knock additive to mitigate the issue. Once the fuel is nearly used up, quickly refill with 95-octane. Develop the habit of checking the octane rating label on the pump before refueling to avoid mistakes in a rush. If the engine shows obvious abnormalities, such as a screeching sound, go directly to a professional repair shop for inspection.
