What type of engine oil is suitable for the Roewe 350?
3 Answers
Roewe 350's original factory engine oil specification is 5W-30. If owners choose to purchase and replace the oil themselves, they must ensure that the oil specification meets or exceeds the "original factory oil" standard. 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, resulting in smoother cold starts for the vehicle. The latter number represents the oil's kinematic viscosity at 100°C. A higher value indicates better viscosity retention under high temperatures, which can also be understood as superior lubrication performance in high-temperature conditions. The steps for changing the engine oil in a Roewe 350 are as follows: Wait for the engine temperature to cool down, 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. Drain until no more oil flows out. Start the engine and let it run for 30 seconds to allow oil in the main oil passages to drain. Use a specialized wrench to remove the oil filter. Apply a thin layer of new oil to the gasket of the new oil filter and hand-tighten it clockwise. Add new engine oil through the oil filler cap on the engine valve cover. Typically, fill about three-quarters of a standard oil container. Start the engine and let it run for 5 minutes. Check for oil leaks around the drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to ensure the oil level is within the standard range.
Having driven the Roewe 350 for several years, I've found that 5W-30 viscosity oil works best, especially synthetic oil with API SN grade. My car runs smoothly with quiet engine noise and slightly better fuel efficiency. It performs steadily in the hot southern summers and starts easily in the cold northern winters. The oil change interval is typically between 8,000 to 10,000 kilometers, depending on your driving habits—if you often drive on highways, the oil lasts longer; frequent short trips require more frequent changes. I've tried Shell and Mobil brands, both work well—just avoid cheap no-name products. Regularly checking oil level and color is crucial; early detection of issues can prevent major repairs.
As a daily driver of the Roewe 350, 5W-30 full synthetic oil is my top choice—it delivers quick engine response, fuel efficiency, and durability. I opt for API SN grade for its strong engine carbon deposit cleaning performance. In terms of brands, Castrol or Great Wall are reliable with good cost-performance. It's recommended to change the oil every six months or 8,000 kilometers; don't slack off, as this prevents premature engine wear. In northern winters, it ensures smooth starts, and in summer heat, there's no fear of cylinder scoring. When checking the oil, a clean dipstick indicates no impurities. Remember to replace the oil filter with each oil change to protect the entire system.
