Is the MG Engine Domestic or Imported?

MG's engines are joint ventures. MG originates from the British MG Rover Group, which was acquired by Nanjing Automobile Group Co., Ltd. in 2005, including its engine production. MG uses two engine models: the 15S4C and the 15C4E. The 15S4C engine has a maximum horsepower of 120, a maximum power of 88 kW, and a peak torque of 150 N·m. The 15C4E engine has a maximum horsepower of 173, a maximum power of 127 kW, and a peak torque of 275 N·m. For daily maintenance of MG engines, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, choose SD-SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, select CB-CD grade diesel engine oil according to mechanical load, ensuring the standard is not lower than the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will deteriorate over time. After a certain mileage, performance degradation can cause various engine issues. To prevent malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to flush the radiator. Removing rust and scale not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.

How Deep Can Car Scratches Be Polished?

In fact, there are many types of scratches on a car body. They can generally be categorized as follows: vehicles with light scratches; scratches that do not reach the primer—these can usually be handled with polishing. Moderate scratches; if you can clearly see the scratch and feel the color paint layer, the best approach is to take the car to a professional repair shop for treatment, otherwise, polishing may only make the scratches worse. Scratches that have exposed the primer; deep scratches that are clearly visible and expose the primer cannot be polished. Scratches that reach the primer require repainting. To deal with everyday light scratches, you can purchase a good-quality paste scratch remover and prepare a soft car towel. First, clean the scratched area of dust and dirt, then apply a small amount of scratch remover paste and rub repeatedly along the direction of the scratch. These minor scratches can be easily removed. For moderate scratches (those who are skilled can follow this method), we recommend a two-step process: grinding and polishing. First, prepare a solid cleaning wax. Use a car towel or sponge to apply the cleaning wax, rubbing evenly and repeatedly along the direction of the scratch until the scratch disappears and the area becomes slightly matte. Next, use a clean car cloth to remove any residual cleaning wax. Finally, you can use scratch remover wax, following the method for light scratches, to further polish and refine the area.

What are the symptoms of spark plug problems?

Spark plug failure can directly cause various issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in starting, which affects the normal operation of the vehicle. Severe erosion of the spark plug, scarring or damage at the top of the spark plug, or melted and eroded electrodes all indicate that the spark plug is damaged and should be replaced. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition. A normal spark plug has an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is contaminated with oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs of scarring, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or the air-fuel mixture is too rich, with oil creeping up.

Which is better for Passat: 5W30 or 5W40?

The original engine oil brand for Passat is Castrol. If you want to change the oil during later maintenance, you can choose from brands such as Shell, Mobil, Castrol, and Total. The official Passat manual recommends oil models of 0W-40 and 5W-40. Any oil model that meets these two specifications can be used. 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 temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Passat is as follows: Wait for the engine temperature to drop and for the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until it stops flowing. Start the engine for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
