What type of oil does Wuling Zhiguang use?
2 Answers
Wuling Zhiguang uses two types of oil: 5W-30 and 0W20. If you want to change the oil during later maintenance, you can choose brands like Mobil, Shell, Castrol, or Great Wall. In the south, it's recommended to use oil with a higher viscosity, above 40, while in the north, 5W30 is sufficient. If the temperature drops to -30 degrees Celsius, opt for 0W20. The viscosity of oil changes with temperature, so it's essential to pay special attention 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, ensuring smoother cold starts for the car. The latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be interpreted as better lubrication performance under high-temperature conditions. The method for changing the oil in Wuling Zhiguang is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out. Use a specialized 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 engine valve cover's oil filler port. Typically, fill up to three-quarters of the oil container. Start the engine and let it run for 5 minutes. Check for any oil 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 if the engine oil level is within the standard range.
My Wuling Zhiguang has been running for almost ten years, and I've always used 10W-40 engine oil. When I first bought the new car, the salesperson recommended using mineral oil with an SG grade or above, saying that the 1.0-liter small horsepower engine doesn't bear heavy loads, so this type of oil is sufficient. For daily city driving, carrying small loads or for family use, an oil change interval of 5,000-7,000 kilometers is appropriate. I usually get it changed at small shops—it's cheaper and more convenient. When choosing oil, avoid options that are too thick or too thin, as it might affect lubrication, causing issues like slow starts in winter or slightly increased fuel consumption. Remember to maintain it on time, and the engine will have fewer problems.
