Can Sinopec and PetroChina gasoline be mixed?
2 Answers
Sinopec and PetroChina gasoline can be mixed. Fueling precautions are: 1. Use automotive gasoline only - improper fuel entering the fuel system may damage both the fuel system and engine; 2. Do not use gasoline containing methanol or alcohol; 3. Avoid spilling fuel on painted surfaces to prevent paint damage; 4. If the fuel door is frozen and cannot be opened, gently push or tap the fuel door to remove ice; 5. Prevent excessive fuel pressure that may cause spraying; 6. Insert the fuel nozzle deep into the tank to avoid overflow or spillage which could lead to fire or explosion; 7. Touch the vehicle body to discharge static electricity before opening the fuel filler flap or contacting the fuel nozzle, and do not re-enter the vehicle during refueling to prevent static buildup.
Having driven for many years, I often encounter situations at different gas stations. Mixing PetroChina and Sinopec fuels is generally safe as long as the octane ratings are the same, such as both being 92 or 95. This is because national standards unify fuel quality, and the oils produced by PetroChina and Sinopec are compatible in composition, with only minor differences in additives that engine designs can handle. However, it's important to avoid mixing fuels of different octane ratings, as this could lead to carbon buildup or engine knocking. It's recommended to keep the fuel tank at least half full during each refill to minimize the impact of residual old fuel. If the vehicle experiences shaking, promptly check the spark plugs and oxygen sensors. In the long run, choosing reputable gas stations is key to reducing the risk of mixing with substandard fuels.
