What are the precautions for switching from 95 to 92 gasoline?

The precautions for switching from 95 to 92 gasoline are: 1. Check whether the car can use 92 gasoline; 2. Do not mix 95 gasoline and 92 gasoline in the fuel tank for a long time. The precautions for refueling are: 1. Use automotive gasoline, as inappropriate fuel entering the fuel system may damage the fuel system and engine; 2. Do not use gasoline containing methanol or alcohol; 3. Avoid spilling fuel on the paint surface to prevent damage; 4. If the fuel tank door is frozen and cannot be opened, gently push or tap the fuel tank door to remove the ice and open it; 5. Prevent excessive fuel pressure from causing spraying; 6. Insert the fuel nozzle deep into the fuel tank to avoid fuel overflow or spillage, which may cause fire and explosion; 7. Before opening the fuel filler cover or touching the fuel nozzle, touch the car body to release static electricity, and do not re-enter the vehicle during refueling to avoid generating static electricity.
A few days ago, I was thinking about switching from 95-octane fuel to 92 to save some money, especially with the soaring gas prices. My car is three years old, and the engine doesn’t have any special requirements. First, I checked the manual to confirm that my car is compatible with 92-octane fuel—some high-compression engines might experience knocking (a rattling sound) if switched, which could affect performance. When making the switch, it’s best not to rush. I recommend filling only half a tank of 92-octane the first time, mixing it with the remaining 95-octane fuel, and driving a few hundred kilometers to observe the engine’s response. If you notice slower acceleration or unusual noises, switch back to 95 immediately to avoid damage. Keep an eye on fuel consumption changes—92-octane is cheaper but might be slightly less efficient, and long-term use could lead to more carbon buildup. To mitigate this, I plan to add a bottle of fuel system cleaner every other month for maintenance. Overall, it’s important to test carefully and avoid risks. If issues arise, visiting a repair shop would be a hassle. This approach balances cost savings and safety—I’ve tried it twice so far, and it’s been working fine.
