What does 0W30 engine oil mean?

The number 0 before the W represents the viscosity at low temperatures. The smaller the number, the better the fluidity at low temperatures and the stronger the cold resistance. The number 30 refers to the viscosity at 100°C. The larger the number, the higher the viscosity and the better the high-temperature resistance. 0W30 engine oil means that the oil can flow normally at -35 degrees Celsius. The viscosity of engine oil should not be too high or too low. If the viscosity is too low, it will increase engine wear. If the viscosity is too high, it will affect the increase in resistance during engine operation, leading to reduced engine power and increased fuel consumption. When the engine is running, the oil forms a film on the surfaces of various engine components, which can reduce friction between them and lower the operating resistance within the engine. If the oil viscosity is too low, the oil cannot form a stable film, which will exacerbate engine wear. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity. 0W is -35°C; 5W is -30°C; 10W is -25°C; 15W is -20°C; 20W is -15°C; 25W is -10°C. The lower the number, the smoother the cold start of the vehicle. The second number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil can maintain its viscosity at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. Relatively speaking, the better the low-temperature fluidity, the smoother the cold start for the vehicle, and the better the protection for the engine. For fully synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. For semi-synthetic oil, the replacement interval is slightly shorter, requiring replacement every 7,000 kilometers or six months. When choosing engine oil, the following points should be noted: Engine oil should be selected according to the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oil should be preferred. Multi-grade oil is economical, long-lasting, and efficient, providing better protection for the engine. Due to its characteristics, multi-grade oil may appear darker and have lower oil pressure than conventional oil during use, which is normal. Since engine oil significantly affects the performance and lifespan of the engine, it should be strictly selected according to the specifications in the vehicle's manual, including the same series, service grade, and viscosity grade. The oil recommended in the vehicle's manual is based on the engine's performance and the temperature conditions of the sales region, providing certain guidance and leaving a considerable safety margin.

How to fold down the rear seats of an old C5?

Press the rear seat folding switch, pull the seat forward with your hand, and fold down the seat. You need to press the switch firmly. When folding down the left seat, only a single seat can be folded down. When folding down the right seat, two seats can be folded down simultaneously, which is called 2/3 split folding. When all three seats are folded down, it is called full folding.

How to Remove Dried Car Wax from Paint?

Dried car wax on the paint needs to be removed with alcohol scrubbing. Here are detailed information about car wax: 1. Definition: Car wax is a protective substance for automotive paint surfaces. It is a chemical material applied to the car's paint surface to protect it while also serving aesthetic purposes. Car wax primarily consists of natural or synthetic waxes, which penetrate into the paint's micro-crevices to create a smooth surface. 2. Function: Besides giving the vehicle's surface a glossy appearance, waxing effectively protects the paint. Additionally, it prevents static electricity generation during driving and shields against rainwater erosion.

Is CVT Transmission Fluid Universal?

CVT transmission fluid is not universal. Recommended CVT fluid change intervals: For new vehicles, optimal maintenance suggests replacement every 40,000-60,000 km or 2 years. For repaired transmissions, mandatory first maintenance at 3,000 km followed by annual or 20,000 km intervals. Properly maintained automatic transmissions can last 10 years without repair, while unmaintained ones average about 5 years. Dual-clutch transmission fluids: Dual-clutch transmissions use two types: standard gear oil for gear lubrication (similar to manual transmission fluid but with better performance) and control system fluid (identical to ATF).
