What does 10w30 engine oil mean?

In 10w30 engine oil, the 'w' stands for winter, '10' indicates the oil's cold start performance—the smaller the number, the better the oil's cold resistance. '30' represents the oil's kinematic viscosity standard at 100 degrees Celsius. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts, thereby reducing wear; 2. To carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine; 3. To circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of parts through the flow of the lubricating oil. Signs that engine oil needs to be changed include: 1. Checking the oil's viscosity—if it has no viscosity, the oil needs to be changed; 2. The oil's color turns black; 3. Excessive black particles, metal shavings, or carbon deposits in the oil; 4. The oil's smell is off.

Why can some turbocharged cars use lower-grade gasoline?

The reasons why some turbocharged cars can use lower-grade gasoline are: 1. The engine is specially designed; 2. The cylinder pressure is reduced. Refueling precautions: 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 ice and open it; 5. Prevent excessive fuel pressure from causing spraying; 6. Insert the fuel nozzle deep into the tank to avoid fuel overflow or spillage, which may cause fire and explosion; 7. Touch the car body to release static electricity before opening the fuel filler cover or contacting the fuel cavity nozzle, and do not re-enter the vehicle during refueling to avoid generating static electricity.
